6.2 CPU Registers
6.2.1 General-purpose registers
Sixteen 8-bit general-purpose registers are available. Two 8-bit registers can be also used in pairs as a 16-bit register. Of the 16-bit registers, four can be used in combination with an 8-bit register for address expansion as 24bit address specification registers. Eight banks of these registers are available which can be selected by using software or the context switching function. The general-purpose registers except V, U, T, and W registers for address expansion are mapped to the internal RAM. Figure 6-5. General-Purpose Register Format

6.2.3 Special function registers (SFRs) The special function registers, such as the mode registers and control registers of the internal peripheral hardware, are registers to which special functions are allocated. These registers are mapped to a 256-Byte space of addresses 0FF00H through 0FFFFHNote. Note On execution of the LOCATION 0 instruction. FFF00H through FFFFFH on execution of the LOCATION 0FH instruction. Caution Do not access an address in this area to which no SFR is allocated. If such an address is accessed by mistake, the PD784038Y may be in the deadlock status. This deadlock status can be cleared only by inputting the RESET signal. Table 6-1 lists the special function registers (SFRs). The meanings of the symbols in this table are as follows: * Symbol ............................... Symbol indicating an SFR. the C compiler (CC78K4). * R/W .................................... Indicates whether the SFR is read-only, write-only, or read/write. R/W : Read/write R W : Read-only : Write-only This symbol is reserved for NEC's assembler
(RA78K4). It can be used as an sfr variable by the #pragma sfr command with
* Bit units for manipulation .. Bit units in which the value of the SFR can be manipulated. SFRs that can be manipulated in 16-bit units can be described as the operand sfrp of an instruction. To specify the address of this SFR, describe an even address. SFRs that can be manipulated in 1-bit units can be described as the operand of a bit manipulation instruction. * After reset .......................... Indicates the status of the register when the RESET signal has been input.

7.3 Real-Time Output Port
The real-time output port outputs data stored in a buffer in synchronization with the coincidence interrupt generated by timer/counter 1 or with an external interrupt. As a result, pulses without jitter can be output. The real-time output port is therefore ideal for applications where arbitrary patterns must be output at specific intervals (such as open loop control of a stepping motor). The real-time output port mainly consists of port 0 and port 0 buffer registers (P0H and P0L) as shown in Figure 7-4. Figure 7-4. Block Diagram of Real-Time Output Port

7.4 Timer/Counter
Three units of timers/counters and one unit of timer are provided. Because a total of seven interrupt requests are supported, these timers/counters and timer can be used as seven units of timers/counters. Table 7-2. Operations of Timers/Counters

7.6 A/D Converter
An analog-to-digital (A/D) converter with eight multiplexed inputs (ANI0 through ANI7) is provided. This A/D converter is of successive approximation type. The result of conversion is retained by an 8-bit A/D conversion result register (ADCR). Therefore, high-speed, high-accuracy conversion can be performed (conversion time: approx. 7.5 s at fCLK = 16 MHz). A/D conversion can be started in either of the following two modes: * Hardware start: Conversion is started by trigger input (INTP5). * Software start: Conversion is started by setting a bit of the A/D converter mode register (ADM). After started, the A/D converter operates in the following modes: * Scan mode: Two or more analog inputs are sequentially selected, and data to be converted are obtained from all the input pins. * Select mode: Only one analog input pin is used to continuously obtain converted values. These operation modes and whether starting or stopping the A/D converter are specified by the ADM. When the result of conversion is transferred to the ADCR, interrupt request INTAD is generated. By using this request and macro service, the converted values can be successively transferred to the memory. Figure 7-7. Block Diagram of A/D Converter

7.7 D/A Converter
Two circuits of digital-to-analog (D/A) converters are provided. These D/A converters are of voltage output type and have a resolution of 8 bits. The conversion method is of R-2R resistor ladder type. By writing a value to be output to an 8-bit D/A conversion value setting register (DACSn: n = 0 or 1), an analog value is output to the ANOn (n = 0 or 1) pin. The output voltage range is determined by the voltage applied across the AVREF2 and AVREF3 pins. Because the output impedance is high, no current can be extracted from the output. If the impedance of the load is low, insert a buffer amplifier between the load and output pin. The ANOn pin goes into a high-impedance state while the RESET signal is low. When the RESET signal is deasserted, DACSn is cleared to 0. Figure 7-8. Block Diagram of D/A Converter

7.8.1 Asynchronous serial interface/3-wire serial I/O (UART/IOE)
Two channels of serial interfaces that can select an asynchronous serial interface mode and 3-wire serial I/O mode are provided. (1) Asynchronous serial interface mode In this mode, data of 1 byte following the start bit is transferred or received. Because an on-chip baud rate generator is provided, a wide range of baud rates can be set. Moreover, the clock input to the ASCK pin can be divided to define a baud rate. When the baud rate generator is used, a baud rate conforming to the MIDI standard (31.25 kbps) can be also obtained. Figure 7-10. Block Diagram in Asynchronous Serial Interface Mode

(2) 3-wire serial I/O mode In this mode, the master device starts transfer by making the serial clock active and transfers 1-byte data in synchronization with this clock. This mode is used to communicate with a device having the conventional clocked serial interface. Basically, communication is established by using three lines: one serial clock (SCK) and two serial data (SI and SO) lines. Generally, a handshake line is necessary to check the communication state.

(1) 3-wire serial I/O mode This mode is to communicate with devices having the conventional clocked serial interface. Basically, communication is established in this mode with three lines: one serial clock (SCK0) and two serial data (SI0 and SO0) lines. Generally, a handshake line is necessary to check the communication status. (2) 2-wire serial I/O mode This mode is to transfer 8-bit data by using two lines: serial clock (SCL) and serial data bus (SDA). Generally, a handshake line is necessary to check the communication status. (3) I2C (Inter IC) bus mode This mode is to communicate with devices conforming to the I2C bus format. This mode is to transfer 8-bit data with two or more devices by using two lines: serial clock (SCL) and serial data bus (SDA). During transfer, a "start condition", "data", and "stop condition" can be output onto the serial data bus. During reception, these data can be automatically detected by hardware.

Clock Output Function
The operating clock of the CPU can be divided and output to an external device. The pin that outputs the clock can also be used as a 1-bit port. When this function is used, the local bus interface cannot be used because the ASTB and CLKOUT pins are multiplexed. Figure 7-13. Block Diagram of Clock Output Function

7.10 Edge Detection Function
The interrupt input pins (NMI and INTP0 through INTP5) are used not only to input interrupt requests but also to input trigger signals to the internal hardware units. Because these pins operate at an edge of the input signal, they have a function to detect an edge. Moreover, a noise reduction circuit is also provided to prevent erroneous detection due to noise.

Note
INTP0 can select a sampling clock.
7.11 Watchdog Timer
A watchdog timer is provided to detect a hang up of the CPU. This watchdog timer generates a non-maskable interrupt unless it is cleared by software within a specified interval time. Once enabled to operate, the watchdog timer cannot be stopped by software. Whether the interrupt by the watchdog timer or the interrupt input from the NMI pin takes precedence can be specified.

8. INTERRUPT FUNCTION
As the servicing in response to an interrupt request, the three types shown in Table 8-1 can be selected by program. Table 8-1. Servicing of Interrupt Request
Servicing Mode Vectored interrupt Entity of Servicing Software Servicing Branches and executes servicing routine (servicing is arbitrary). Context switching Automatically switches register bank, branches and executes servicing routine (servicing is arbitrary). Macro service Firmware Executes data transfer between memory and I/O (servicing is fixed) Retained Contents of PC and PSW Saves to and restores from stack. Saves to or restores from fixed area in register bank
8.1 Interrupt Sources
Table 8-2 shows the interrupt sources available. As shown, interrupts are generated by 24 types of sources, execution of the BRK instruction or BRKCS instruction, or an operand error. The priority of interrupt servicing can be set to four levels, so that nesting can be controlled during interrupt servicing and that which of the two or more interrupts that simultaneously occur should be serviced first. When the macro service function is used, however, nesting always proceeds. The default priority is the priority (fixed) of the service that is performed if two or more interrupt requests, having the same request, simultaneously generate (refer to Table 8-2).

8.2 Vectored Interrupt
Execution branches to a servicing routing by using the memory contents of a vector table address corresponding to the interrupt source as the address of the branch destination. So that the CPU performs interrupt servicing, the following operations are performed: * On branching: Saves the status of the CPU (contents of PC and PSW) to stack * On returning: Restores the status of the CPU (contents of PC and PSW) from stack To return to the main routine from an interrupt service routine, the RETI instruction is used. The branch destination address is in a range of 0 to FFFFH. Table 8-3.

8.3 Context Switching
When an interrupt request is generated or when the BRKCS instruction is executed, a predetermined register bank is selected by hardware. Context switching is a function that branches execution to a vector address stored in advance in the register bank, and to stack the current contents of the program counter (PC) and program status word (PSW) to the register bank. The branch address is in a range of 0 to FFFFH. Figure 8-1. Context Switching Operation When Interrupt Request Is Generated

Macro Service
This function is to transfer data between memory and a special function register (SFR) without intervention by the CPU. A macro service controller accesses the memory and SFR in the same transfer cycle and directly transfers data without loading it. Because this function does not save or restore the status of the CPU, or load data, data can be transferred at high speeds. Figure 8-2. Macro Service

Each time macro service request (INTST) is generated, the next transfer data is transferred from memory to TXS. When data n (last byte) has been transferred to TXS (when the transfer data storage buffer has become empty), vectored interrupt request (INTST) is generated. (2) Reception of serial interface

(3) Real-time output port INTC10 and INTC11 serve as the output triggers of the real-time output port. The macro services for these can set the following output pattern and intervals simultaneously. Therefore, INTC10 and INTC11 can control two stepping motors independently of each other. They can also be used for PWM output or to control DC motors.

Match (SFR) P0L INTC10 Output latch P00-P03 TM1 CR10 (SFR)
Each time macro service request (INTC10) is generated, the pattern and timing are transferred to the buffer register (P0L) and compare register (CR10), respectively. When the contents of the timer register 1 (TM1) coincide with those of CR10, INTC10 is generated again, and the contents of P0L are transferred to the output latch. When Tn (last byte) has transferred to CR10, vectored interrupt request (INTC10) is generated. The same applies to INTC11.

9. LOCAL BUS INTERFACE
The local bus interface can connect an external memory or I/O (memory mapped I/O) and support a memory space of 1 MByte (refer to Figure 9-1). Figure 9-1. Example of Local Bus Interface

Memory Expansion
The memory capacity can be expanded in seven steps, from 256 Bytes to 1 MByte, by connecting an external program memory and data memory.

9.2 Memory Space
The 1-MByte memory space is divided into eight spaces of logical addresses. Each space can be controlled by using the programmable wait function and pseudo static RAM refresh function. Figure 9-2. Memory Space

9.3 Programmable Wait
The memory space can be divided into eight spaces and wait states can be independently inserted in each of these spaces while the RD and WR signals are active. Even when a memory with a different access time is connected, therefore, the efficiency of the entire system does not drop. In addition, an address wait function that extends the active period of the ASTB signal is also provided so as to have a sufficient address decode time (this function can be set to the entire space).
9.4
Pseudo Static RAM Refresh Function
The following refresh operations can be performed: * Pulse refresh: A bus cycle that outputs a refresh pulse to the REFRQ pin at a fixed cycle is inserted. The memory spaces is divided into eight spaces, and a refresh pulse can be output from the REFRQ pin while a specified memory space is accessed. Therefore, the normal memory access is not kept to wait by the refresh cycle. * Power-down self-refresh: The low level is output to the REFRQ pin in the standby mode to retain the contents of the pseudo static RAM.
9.5
Bus Hold Function
A bus hold function is provided to facilitate connection of a DMA controller. When a bus hold request signal (HLDRQ) is received from an external bus master, the address bus, address/data bus, and ASTB, RD, and WR pins go into a high-impedance state when the current bus cycle has been completed. This makes the bus hold acknowledge (HLDAK) signal active, and releases the bus to the external bus master. Note that, while the bus hold function is used, the external wait function and pseudo static RAM refresh function cannot be used.

10. STANDBY FUNCTION
This function is to reduce the power dissipation of the chip, and can be used in the following modes: * * HALT mode: Stops supply of the operating clock to the CPU. This mode is used in combination with the normal operation mode for intermittent operation to reduce the average power dissipation. IDLE mode: Stops the entire system with the oscillation circuit continuing operation. The power dissipation in this mode is close to that in the STOP mode. However, the time required to restore the normal program operation from this mode is almost the same as that from the HALT mode. * STOP mode: Stops the oscillator and thereby to stop all the internal operations of the chip. Consequently, the power dissipation is minimized with only leakage current flowing. These modes are programmable. The macro service can be started from the HALT mode. Figure 10-1.

11. RESET FUNCTION
When the low level is input to the RESET pin, the internal hardware is initialized (reset status). When the RESET pin goes high, the following data are set to the program counter (PC). * Lower 8 bits of PC: contents of address 0000H * Middle 8 bits of PC: contents of address 0001H * Higher 4 bits of PC: 0 Program execution is started from a branch destination address which is the contents of the PC. Therefore, the system can be reset and started from any address. Set the contents of each register by program as necessary. The RESET input circuit has a noise reduction circuit to prevent malfunctioning due to noise. This noise reduction circuit is a sampling circuit by analog delay. Figure 11-1. Accepting RESET Signal

NOTES FOR CMOS DEVICES
1 PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note: Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and ultimately degrade the device operation. Steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. Environmental control must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using insulators that easily build static electricity. Semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. All test and measurement tools including work bench and floor should be grounded. The operator should be grounded using wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need to be taken for PW boards with semiconductor devices on it.
2 HANDLING OF UNUSED INPUT PINS FOR CMOS
Note: No connection for CMOS device inputs can be cause of malfunction. If no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. CMOS device behave differently than Bipolar or NMOS devices. Input levels of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused pin should be connected to VDD or GND with a resistor, if it is considered to have a possibility of being an output pin. All handling related to the unused pins must be judged device by device and related specifications governing the devices.
3 STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note: Power-on does not necessarily define initial status of MOS device. Production process of MOS does not define the initial operation status of the device. Immediately after the power source is turned ON, the devices with reset function have not yet been initialized. Hence, power-on does not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the reset signal is received. Reset operation must be executed immediately after power-on for devices having reset function.
