BLOCK DIAGRAM AND OPERATIONAL OVERVIEW
ARCHITECTURAL OVERVIEW
1.
ARCHITECTURAL OVERVIEW
The Z86230 is a stand-alone integrated circuit, capable of processing Extended Data Services (XDS) in Field 2 of the Vertical Blanking Interval (VBI) of a video frame. This device conforms to the transmission format defined in the Television Decoder Circuits Act of 1990, in accordance with the Electronics Industry Association specification EIA-608A and EIA-744A. The XDS data is processed to provide either a Program Blocking signal (PB) or a recovered XDS data packet. The PB matches the contents of the recovered Content Advisory packet to the user selections input on the decoder. On-chip XDS filters in the Z86230 are fully-programmable, enabling recovery of only those XDS data packets selected for use in TVs, VCRs, and Set-Top boxes. In addition, the Z86230 is ideally suited to monitor Picture-In-Picture (PiP) window video for violence blocking and other XDS data services. Highlights of the Z86230 include: 1. A stand-alone Line 21 Decoder for Extended Data Services (XDS). 2. Extractable XDS data from the input video. 3. Full output of a selectable V-Chip Program Blocking signal (PB). 4. Selectable XDS filter parameters from a list of preprogrammed values. 5. Minimal communications and control overhead that provides simple implementation of Violence Blocking and Auto Clock Set Features. 6. Full output of the recovered XDS data through the I2C serial communication port. 7. Two different slave addresses that are selectable in the I2C serial communication port. 8. Selectable NTSC or PAL operation.
1.1 BLOCK DIAGRAM AND OPERATIONAL OVERVIEW
The Z86230 is designed to process XDS data of the television VBI. The device requires both a Composite Video and a horizontal timing signal (HIN/XIN input). Several passive components are required for proper operation. Commands are input to enable the decoder to process and control the V-Chip response to the XDS Content Advisory packet. The Z86230 can also be configured to operate with PAL video signals. In PAL mode, the device decodes information encoded into VBI Line 22. The encoded data must conform to the waveform and command structure defined for NTSC Line 21 operation. Figure 1 illustrates the Functional Block Diagram of the Z86230.

BLOCK DIAGRAM AND OPERATIONAL OVERVIEW
ARCHITECTURAL OVERVIEW
1.1.1 Input Signals
The Composite Video input should be a signal which is nominally 1.0 Volt p-p, with sync tips negative and band limited to 600 kHz. The Z86230 operates with an input level variation of 3 dB. The HIN/XIN input signal is required to bring the voltage-controlled oscillator (VCO) close to the required operating frequency.
1.1.2 Video Input Signal Processing
The Composite Video input is AC-coupled to the device where the sync tip is internally clamped to a fixed reference voltage. The Data Slicer extracts a clean CMOS-level data signal by slicing the signal at its midpoint. The slice level is established on an adaptive basis during Line 21. The Sync Slicer processes the clamped Composite Video signal to extract Composite Sync. This signal is used to lock the internal logic to the incoming video. The slice level is stored on the sync slice capacitor, CSYNC. The Data Clock Recovery circuit operates in conjunction with the Horizontal (H) Lock circuit. These circuits produce a data clock (DCLK) and, when Line 21 code appears, DCLK phase lock is achieved during the clock run-in burst (used to reclock the sliced data). When phase lock is established, DCLK is maintained until a change in the video signal occurs.
1.1.3 Voltage-Controlled Oscillator (VCO) and One-Shot
All internal timing and synchronizing signals are derived from the on-board 12MHz VCO. Its output is the DCLK signal used to drive the Horizontal and Vertical counter chains. The One-Shot circuit produces a horizontal timing signal derived from the incoming video. The VCO exhibits stable gain characteristics and good power supply rejection.
1.1.4 Timing and Counting Circuits
The DCLK is divided to generate the horizontal timing signals H and 2H.The H signal is further divided in the line counter (LINE CNTR) and field counter (FLD CNTR) to produce the various decodes used to establish vertical lock and to time the control functions required for proper operation.
1.1.5 Command Processor
The Command Processor controls the manipulation of the data for storage. During the recovery time, the command processor, in conjunction with the data recovery circuits, recovers the XDS data.

BLOCK DIAGRAM AND OPERATIONAL OVERVIEW
1.1.6 Decoder Control Circuit
The Decoder Control circuit block is the users communications port. This circuit converts the information from the control port into the internal control signals required to establish the operating mode of the decoder. The Z86230 responds to its slave address for both the READ and WRITE conditions. If the READ bit is Low (indicating a WRITE sequence), then the Z86230 responds with an Acknowledge. The master should then send an address byte followed by a data byte. If the READ bit is High (indicating a READ sequence), then the Z86230 responds with an Acknowledge followed sequentially by a status byte and a data byte. READ data is only available through indirect addressing. WRITE addressing exhibits both indirect and direct modes. The busy bit in the status byte indicates if the WRITE operation is completed or if READ data is available.
1.1.7 Voltage/Current Reference
The Voltage/Current reference circuit uses an externally connected resistor to establish the reference levels that are used throughout the Z86230. For a minimal investment, the use of an external resistor can also provide improved internal precision.

I2C BUS OPERATION

SERIAL COMMUNICATIONS INTERFACE
Commands and data are sent to and from the Z86230 through its I 2C serial communications interface. This port is the path for setting the configuration and operational modes of the device. The interface is also used as the port for outputting the recovered XDS data.
4.1 I2C BUS OPERATION
The Z86230 supports a bidirectional 2-wire bus and data transmission protocol. The bus is controlled by the master device, which generates the serial clock (SCLK), controls the bus access, and generates the START and STOP conditions. The serial data (SDA) pin is the bidirectional data line. The Z86230 is a slave device with two possible slave addresses. When the I2C SEL pin is Low, the slave address is 28h for WRITE and 29h for READ. When the I2C SEL pin is High, the slave address is 2Ah for WRITE and 2Bh for READ. The Z86230 can receive or transmit data under control of the master device. Communication is initiated when the master device sends the START condition followed by the Z86230 Slave Address READ byte or Slave Address WRITE byte. The Z86230 responds with an Acknowledge. The I2C RD/WR bit is the Least Significant Bit (LSB) of the I2C addresses listed below in Table 4.
TABLE 4. Z86230 I2C SLAVE ADDRESSES READ 1st I2C Address 2nd I2C Address 2nd I2C Address. 29h 2Bh WRITE 28h 2Ah

4.1.1 The I2C Bus Protocol
The Bus Protocol requires that: 1. Data transfer can only be started when the bus is not busy. 2. During data transfer, data transitions must not occur while the clock is High.
4.1.2 Bus Conditions
Bus Conditions are defined as:
Not Busy. Data and Clock lines are both High. START. A High-to-Low transition of the SDA line while the SCLK line is High. STOP. A Low-to-High transition of the SDA line while the SCLK line is High.

I2C BUS OPERATION
SERIAL COMMUNICATIONS INTERFACE
Acknowledge. When addressed, the receiving device must output an Acknowl-
edge after the reception of each byte. The master device must generate the clock for the Acknowledge bit. Acknowledge is SDA = Low. Not Acknowledge (NACK) is SDA = High.
Data. The data (SDA) is output by the transmitting device on the falling edge of SCLK, MSB first. The receiving device interprets the data, MSB first, on the rising edge of SCLK.
Communication with the Z86230 is initiated when the master device sends the Z86230 slave address following a START condition. The Z86230 has a preset, single, seven-bit slave address. The Z86230 responds with an Acknowledge. The eighth bit of the slave address is driven High for READ operations and Low for WRITE operations.
4.1.3 Writing to the I2C Bus
Commands and data are written to the Z86230 using the I2C bus interface. The device is enabled when an I2C START condition, followed by its Slave Address WRITE byte, is received. A WRITE operation is ended and the bus is disabled upon the receipt of an I2C STOP condition. Any number of command bytes, up to 32, may be sent after the device is WRITE-enabled. Each of these commands is either 1 or 2 bytes in length. The device executes the commands in order of receipt. Overflowing the 32 byte buffer causes improper operation. The RDY bit of the Serial Status Register (SSR) may be read to determine if there is room in the command buffer for at least 2 bytes of command data. The Status register data is output immediately following the receipt of the Slave Address READ. The first byte of a 2-byte command is always written first. The master's sequence for writing a 2-byte command, followed by a 1-byte command is displayed in the following example:
Start Slave_Address_Write/Slave ACK CMD1_Write/Slave ACK DATA1_Write/Slave ACK CMD2_Write/Slave ACK Stop

4.1.4 Reading Data Using the I2C Bus
The Z86230 I2C bus supports READ sequences up to 34 bytes in length. All READ sequences output the Serial Status Register (SSR) as the first output byte. The data to be read is selected by sending the READ BANK SELECT (RBS) command. Four READ bank modes are available in the Z86230:
TABLE 5. Z86230 I2C READ BANK SELECT (RBS) COMMAND RBS Command Bank 0 Descriptions A general-purpose bank used to read the Z86230-defined internal registers. The register to be read from Bank 0 is set up manually using the READ SELECT commands, RDS1 and RDS2. These commands load the selected data byte (or pair of bytes) into the first location(s) of Bank 0, and set the DAV bit to indicate the availability of data. A special purpose bank provided to facilitate the reading of commonly accessed data. This bank contains the Program Blocking registers and permits direct, multibyte reading of internal registers 08h through 11h. These registers are described in the internal register section. When it is selected, the sequence of bytes read is SSR, followed by internal registers 08h, 09h, 0Ah, 0Bh, 0Ch, 0Dh, 0Eh, 0Fh, 10h, and 11h. A special purpose bank provided to facilitate the reading of commonly accessed data. This bank contains the XDS Program Name data from the most recently received current class type 3 packet. A special purpose bank provided to facilitate the reading of commonly accessed data. This bank contains the XDS Network Name and Call Letter data. The first 26 bytes has the XDS Network Name from the most recently received XDS channel class type 1 packet. Bytes 26 through 31 has the XDS Call Letters data from the most recently received XDS channel class type 2 packet
Bank 1
Bank 2
Bank 3
NOTE: Banks 2 and 3 are 33 bytes in length. Byte 32 of these banks contains an 8 bit checksum. The checksum is calculated such that the addition of the 32 data bytes and the checksum modulo 256 equals zero. The checksum should always be evaluated after reading this data to ensure that the XDS data is not being updated during the READ operation. The result is a meaningless combination of two unrelated XDS data packets. If a bad checksum is encountered, the READ operation should be repeated.

I2C BUS OPERATION
SERIAL COMMUNICATIONS INTERFACE
All READ sequences output the SSR first. If the Serial Status register DAV bit is set, a 2- or multiple-byte READ sequence can be initiated, beginning with a START condition. If the DAV bit is not set, the I2C master device should not attempt to read any data bytes or the required data can be lost from the Z86230 output registers. The I2C master device should end the READ sequence by failing to acknowledge the received byte. This sequence is repeated until the DAV bit becomes true.
NOTE: In all I2C READ operations (1-, 2- and 3-byte reads are illustrated in Figure 5), the
most recent byte read from the Z86230 should be acknowledged by the master with a Not Acknowledge (NACK). The DAV bit of the Serial Status Register (SSR) is cleared by the master clocking out the eighth bit of the first data byte read. The DAV bit is never cleared by just reading the SSR (One Byte READ) alone. All data is output MSB first.
The master's sequence for reading two data bytes (total of 3 bytes including SSB) from the Z86230 is:
Start Slave_Address_Read/Slave_ACK SS_Byte/Master ACK First_Byte/Master ACK Second_Byte/Master_NACK Stop FIGURE 5. I2C BUS READ (COMMAND) I2C One-Byte READ (Status Only)

NACK STOP
NOTE: In all I2C READ operations, the most recent byte read from the Z86230 must be acknowledged by the master with a NACK (Not ACKnowledge).
4.1.5 Clock and Data Transitions
The SCLK and SDA bus lines are normally pulled High with a resistor. Data on the SDA bus may only change during SCLK Low time periods. Data changes during SCLK High periods indicate a START or STOP condition as defined in Table 6.
4.1.6 START Condition
A High-to-Low transition of SDA with SCLK High is a START condition which must precede any other command.

SERIAL COMMUNICATIONS INTERFACE
I2C BUS OPERATION
4.1.7 STOP Condition
A Low-to-High transition of SDA with SCLK High is a STOP condition which terminates all communications.
4.1.8 Acknowledge
All address and data words are serially transmitted to and from the Z86230 in eight bit words. A ninth bit time is used for the Acknowledge. The acknowledging device pulls the SDA bus Low during the ninth bit. A Not Acknowledge (NACK) is returned by SDA = High during the ninth clock time.

5.1 SERIAL PORT COMMANDS
The commands must be contained within the Start-Slave Address-etc. sequence.
NOTE: In the following Command descriptions, the letter h following a command code
designates hexadecimal notation. 5.1.1 RESET = FBh RESET is a 1-byte command. The RESET command establishes all of the speci-
fied default settings in the device, but it does not reset the serial port itself. The
RESET command must be followed by a no operation (NOP) command, because RESET stays active until deactivated by the NOP. This sequence can be entered without the RDY bit being set. 5.1.2 NOP = 00h NOP is a 1-byte command. The NOP command does not affect the status of the RDY bit in the Serial Status Register (SSR) and can be executed independent of the RDY status. TABLE 7.

5.2.1 READ Bank Select (RBS = FDh) RDS1 is a 2-byte command to select the read data bank. The lower 2 bits of the second data byte select one of four banks of up to 33 bytes. A subsequent I2C READ deciphers data from the specified bank. 5.2.2 READ SELECTs (RDS1 = 40h-51H) RDS1 is a 1-byte command used to initiate a 1-byte READ sequence. This activity is performed by moving the contents of the register identified by the address field (AD00:04) of the command to the first location of READ bank 0. Addresses 00h- 11h are valid in the RDS1 command field AD00:04.

CONTROL REGISTERS
D1-D7-Res. Reserved. These bits must be kept Low(0).
6.2 XDS DATA RECOVERY
The Z86230 is able to recover Extended Data Services (XDS) information from the input video signal. This data, formatted according to EIA-608A, can contain a wide variety of information about current and future programs, the channel currently tuned, other channels, and miscellaneous data, including time of day. XDS data packets are tagged according to a Class/Type system defined by EIA608A. The Z86230 can be programmed to filter the XDS data stream to extract only the classes of interest to the application. An additional level of filtering is provided that permits selection of certain groups of packets that are of use in specific applications. XDS filtering reduces the traffic on the serial bus, reduces the load of the TV/VCR control processor, and simplifies external XDS decoding. XDS data recovery is enabled by selecting one or more classes in the XDS Filter Register. Optionally, a secondary filter code can be specified which further limits the packets to be recovered. When XDS recovery is enabled, filtered data pairs are loaded into the first two data locations of Bank 0 immediately upon receipt. The DAV bit of the Serial Status Register (SSR) then goes High, indicating the availability of two output bytes. When the XDS Filter Register is set to 00h (the default state), XDS recovery is disabled.
CAUTION: When XDS data recovery is enabled, the external controller should never perform any other read operation, except SSR reads, in the beginning of Field 2. Commands
other than READ SELECTs do not interfere with XDS data recovery regardless of their position in the video frame.
Some examples of Z86230 WRITE commands that could be used to set the XDS Filter Register are indicated in Table 28. The XDS Filter Register bit assignments are defined in Table 30.

6.2.1 Filtered XDS Data Format
Filtered XDS data is output from the Z86230 in the order it is received on Line 21. In other words, think of the Z86230 XDS filter function as creating a new, smaller stream of XDS data packets. This new data stream looks exactly as though the Class and Type specified in the XDS Filter Register (05h) are the only data encoded on Line 21 of Field 2. The filtered data output from the Z86230 is in full compliance with EIA-608 specifications for XDS data streams (headers and control codes intact). Refer to the NOTE paragraph on the next page for a special exception to this rule. XDS data and header information (including START, CONTINUE, and END commands) are passed through the filter for the XDS Class and Type specified in the XDS Filter Register. All other Line 21 data is filtered out. This data does not output or generate a data available flag (DAV) in the Serial Status Register (SSR). To properly read filtered XDS data from the Z86230, the master device must first write the XDS Filter Register (05h) with its required XDS Class and Type information. For example, in the Z86230, in order to extract ONLY the Line 21 Program Rating information, the master must write the value 61h to the XDS Filter Register. The master should then poll the state of the DAV bit in the SSR until
DAV = 1.
As soon as DAV = 1, the master may initiate a 3-byte READ in RBS Read Bank 0 mode (XDS data bytes always arrive in pairs, so it is safe to read the first 2 bytes of read bank 0 when DAV = 1 in the SSB). A 3-byte READ always yields two data bytes, which in this case are the first 2 bytes of the Current Class, Program Rating Type XDS data stream encountered on Line21, Field 2. The master device must then interpret those 2 bytes according to EIA-608 specifications for Current Class, Program Rating Type data. Refer to EIA-608 for the appropriate data formats.

XDS DATA RECOVERY
CONTROL REGISTERS
The XDS filters on the Z86230 greatly reduce the amount of Field 2 data passed on to the master device for further processing and interpretation; however, the master device must still interpret the filtered data stream in accordance with EIA608A. In other words, only the selected XDS data Class and Type packets are chosen. The filtered data stream contains all of the XDS command and data packets. Though the Z86230 filtered data stream is in full compliance with the EIA-608 specification, the master device must still interpret the necessary packets to ensure full compliance with EIA-608A.
NOTE: The Z86230 XDS filter for Program Rating information functions differently than
all other Z86230 predefined XDS filters. This change has been made to minimize the amount of data passed through the Program Rating XDS filter, thereby minimizing the interpretation and communications load on the master device. When the XDS Filter Register is set to 61h (Class=01h (Current), Type=05h (Program Rating) the only data from Line 21 Field 2 that passes through the filter is:
1. Program Rating Packet: [xxh,xxh]. The Current Class Program Rating data byte pair as defined in EIA-608. The program's rating is encoded per EIA-608 in the xxh byte pair. 2. The END Packet [0Fh,CHKSUM]. A 2-byte packet that includes a CHKSUM computed per EIA-608A. The checksum calculation includes the START packet [01h,05h] even though this value was not passed through the filter.

Z86230 COMMANDS AND REGISTERS SUMMARY
6.3 Z86230 COMMANDS AND REGISTERS SUMMARY
TABLE 29. Z86230 SUMMARY OF CONTROL COMMANDS Name RESET Code FBh Function RESET is 1-byte command sequence serial communication. The RESET command establishes all of the specified default settings in the device; however, it does not reset the serial port itself. This sequence can be entered without RDY being set. NOP is a 1-byte command for use in serial communication. The NOP command does not affect the status of the RDY bit in the Serial Status Register (SSR) and can be executed independent of the RDY status. RDS1 is a 1-byte command used to initiate a 1byte READ sequence by moving the contents of the register identified by the address field (AD00:04) of the command to the output register. Addresses 00h-11h are valid in the RDS1 command field AD00:04. RDS2 is a 1-byte command which is used to initiate a 2-byte READ sequence. This activity is accomplished by moving the contents of the two consecutive registers, starting with the one identified by the address portion of the command (AD00:AD04), to the output registers. Only Addresses 00h-10h are valid in the RDS2 command field AD00:04. The WRITE commands require 2 bytes to execute. The first byte is the WRITE command includes the Z86230 register address (AD00:04) being written. The second byte (XXh) is the data to be written. RBS is 2-byte command to select the READ data bank. The 2 LSBs of the second byte (0Xh) select one of four banks of up to 33 bytes. Subsequent I2C READs interpret data from this bank.

DEMONSTRATION PROGRAMS
7.1 COMMUNICATING WITH THE Z86230
Communications with the Z86230 is accomplished using its serial communications interface (it is assumed that the user is familiar with the serial protocol requirements).
NOTE: In the following descriptions, means "press the Enter key".
7.2 I2C OPERATION
The Z86230 is configurable as an I2C slave device. The PC communicates with the Z86230 through its parallel port. Though these programs are not intended as examples of how to program the application they do provide a means of illustrating the serial control process and capability of the Z86230. The three programs available are titled IICO, SCRIPTI and XDSCAP. These programs compile and run satisfactorily with the Z86230 in a test board. Compiled versions are available on disk. Contact your local ZiLOG sales office for further information on these programs.
7.3 IICO PROGRAM
This program sends 1 byte to the Z86230 without checking the status of the RDY bit. The program returns the contents of the Serial Status Register (SSR) after the command is entered. When the program is active the screen displays:
IIC Command Byte >
The user may enter any valid 1-byte command such as FBh (RESET) or 00h (NOP) and then hit the ENTER key. The screen then displays the byte entered and the SSR contents as follows:
IIC Byte = 00 IIC Status = 83h
This example shows that the NOP command was entered. The SSR contents, 83h, indicate that the RDY, FLD, and LOCK bits are High, which implies that the serial port is ready for further input, that the input video signal was in Field 1 at the time the status was read, and that the part is operating in video lock mode. The IICO program is exited by entering a Control+C (^C) character. For example, entering the following two 1-byte commands displays the following:
Reset the part FB, 00

7.5 SCRIPTI PROGRAM
This program is designed to send any number of 1 or 2-byte commands to the Z86230. The list of commands to be executed are contained in Script files that have the extension .SER. For example, a file called FILFA.SER contains the 1-byte command:
{C5, 02} * Set xds filter to all future class
The program is invoked by typing: SI File_name
NOTE: File_name without the .SER extension.
The screen displays:
EEG CCD2 Serial Interface Script Player Version x.xx Slave Address is 28h Script File Done
The responding slave address is reported to the screen. When all of the commands in the file are successfully sent to the Z86230, the PC returns to the system prompt. The program checks the RDY status before sending each byte. If, during the entry of a command, the RDY bit is not found to be a 1 after an extended wait, the program reports the contents of the SSR and then continues checking for RDY.
7.6 SCRIPT FILES
Script files can be generated to perform all of the setup and control functions required to use the part in an application. The script files shown in the following pages are examples used to set up the Z86230 for different operating conditions. Some of the files contain only a single command while others include several commands. The user should refer to Z86230 Commands and Registers Summary for details. Although the following examples are organized according to a particular register, some of the files contain information for several registers.

7.6.2 XDSCAP Program
This program performs the task of XDS data recovery. XDS recovery must first be enabled through the appropriate XDS Filter command. Script file examples for setting the XDS Filter are shown below. The program is invoked by typing: SI File_name When the program is invoked, the PC screen displays:
EEG CCD2 XDS Data Recovery Test Program Version x.xx Slave Address is 28h
The responding slave address is reported to the screen. When communication is acknowledged, the program displays all XDS data recovered from those packets that were enabled through the XDS Filter command:
{01,03}Current Program{00}{0F,7F}....etc
The ASCII characters are displayed as ASCII characters, while the nonprinting characters are displayed by their Hex values within curly braces. Byte pairs, such as Class, Type, are shown as pairs within the curly braces, separated by a comma, for example: {01,03}. If no data is received within approximately 45 seconds, the program times out, reports Data Not Available, and exits.
NOTE: The XDSCAP program can also be exited by entering a Control+C (^C) character.
