Function Descriptor
6.1 Legacy PS/2 Mouse Operating
6.1.1 Operating Mode
There are four operating modes in PS/2 mouse: 6.1.1.1 Reset Mode In this mode a self-test is initiated during power-on or by a Reset command. After reset signal, PS/2 mouse will (1) Send completion code AA & ID code 00. (2) Set default: Sampling rate: 100 reports/s Non-auto-speed Stream mode 2 dot/count Disable 6.1.1.2 Stream Mode The maximum rate of transfer is the programmed sample rate. Data report is transmitted if (1) Switch is pressed (2) Movement has been detect 6.1.1.3 Remote Mode Data is transmitted only in response to a Read Data command. 6.1.1.4 Wrap Mode Any byte of data sent by the system, except hex EC (Reset wrap mode) or hex FF (Reset), is returned by EKM6211.

6.1.2 PS/2 Mouse Data Report
6.1.2.1 In stream mode A data report is sent at the end of a sample interval. 6.1.2.2 In remote mode A data report is sent in response to Read Data command. 6.1.2.3 Data report format
Byte Bit 0 1 2 1 3 4 5 6 7 2 3 0-7 0-7 Description Left button status; 1 = pressed Right button status; 1 = pressed Middle button status; 1 = pressed Reserved X data sign; 1 = negative Y data sign; 1 = negative X data overflow; 1 = overflow Y data overflow; 1 = overflow X data ( D0 - D7 ) Y data ( D0 - D7 )
6.1.3 PS/2 Mouse Data Transmission
EKM6211 generates the clocking signal when sending data to and receiving data from the system. The system requests EKM6211 receive system data output by forcing the DATA line to an inactive level and allowing CLK line to go to an active level. Data transmission frame:
Bit 1 2-9 10 11 Function Start bit ( always 0 ) Data bits ( D0 - D7 ) Parity bit ( odd parity ) Stop bit ( always 1 )
Data Output (data from EKM6211 to system):
If CLK is low (inhibit status), data is no transmission. If CLK is high and DATA is low (request-to-send), data is updated. Data is received from the system and no transmission are started by EKM6211 until CLK and DATA both high. If CLK and DATA both are high, the transmission is ready. DATA is valid prior to the falling edge of CLK and beyond the rising edge of CLK. During transmission, EKM6211 check for line contention by checking for an inactive level on CLK at intervals not to exceed 100u sec.
4* Product Specification (V1.0) 11.15.2003
(This specification is subject to change without further notice)
EKM6211 RF Mouse Rx Controller Contention occurs when the system lowers CLK to inhibit EKM6211 output after EKM6211 has started a transmission. If this occurs before the rising edge of the tenth clock, EKM6211 internal store its data in its buffer and returns DATA and CLK to an active level. If the contention does not occur by the tenth clock, the transmission is complete. Following a transmission, the system inhibits EKM6211 by holding CLK low until it can service the input or until the system receives a request to send a response from EKM6211. Data Input (from system to EKM6211):
The System first checks if EKM6211 is transmitting data. If EKM6211 is transmitting, the system can override the output forcing CLK to an inactive level prior to the tenth clock. If EKM6211 transmission is beyond the tenth clock, the system receives the data. If EKM6211 is not transmitting or if the system choose to override the output, the system force CLK to an inactive level for a period of not less than 100u sec while preparing for output. When the system is ready to output start bit (0), it allows CLK go to active level. If request-to-send is detected, EKM6211 clocks 11 bits. Following the tenth clock, EKM6211 checks for an active level on the DATA line, and if found, force DATA low, and clock once more. If occurs framing error, EKM6211 continue to clock until DATA is high, then clocks the line control bit and request a Resend.
When the system sends out a command or data transmission that requires a response, the system waits for EKM6211 to response before sending its next output.
6.1.4 PS/2 Mouse Error Handling
A Resend command (FE) following receipt of an invalid input or any input with incorrect polarity. If two invalid inputs are received in succession, an error code of hex (FC) is send to the system. The counter accumulators are cleared after receiving any command except "Resend". EKM6211 receives a Resend command (FE), it transmits its last packet of data. In the stream mode "Resend" is received by EKM6211 following a 3-byte data packet transmission to the system. EKM6211 resend the 3-byte data packet prior to clearing the counter. A response is sent within 25 ms if The system requires a response An error is detected in the transmission If EKM6211 is in the stream mode:

EKM6211 RF Mouse Rx Controller The system disables EKM6211 before issuing any command requiring a response. When a command requiring a response is issued by the system, another command should not be issue until either the response is received or 25 ms has passed.
6.1.5 PS/2 Mouse Commands Description
There are 16 valid commands that transmit between the system and EKM6211. The "FA" code is always the first response to any valid input received from the system other than a Set Wrap Mode or Resend command. The following table lists the commands:
Hex Code FF FE F6 F5 F4 F3,XX F2 F0 EE EC EB EA E9 E8,XX E7 E6 Command Reset Resend Set Default Disable Enable Set Sampling Rate Read Device Type Set Remote Mode Set Wrap Mode Reset Wrap Mode Read Data Set Stream Mode Status Request Set Resolution Set Auto-speed Reset Auto-speed Echo code FA,AA,00 XX,(XX,XX) FA FA FA FA,FA FA,00 FA FA FA FA,XX,XX,XX FA FA,XX,XX,XX FA,FA FA FA
The following describes valid commands: 6.1.5.1 Reset (FF) EKM6211 operation: A B C Completion the reset. Transmit FA, AA, 00 to the system. Set default: Sampling rate: 100 reports/s Non auto-speed Stream mode 2 dot/count Disable

(This specification is subject to change without further notice)
EKM6211 RF Mouse Rx Controller 6.1.5.2 Resend (FE) A Any time EKM6211 receives an invalid command, it returns a Resend command to the system. When EKM6211 receives a Resend command, it retransmits its last packet of data. If the last packet was a Resend command, it transmits the packet just prior to the Resend command. In stream mode, if a Resend command is received by EKM6211 immediately following a 3-byte data packet transmission to the system.

6.1.5.3 Set Default (F6) The command reinitializes all conditions to the power-on defaults. 6.1.5.4 Disable (F5) This command is used in the stream mode to stop transmissions from EKM6211. 6.1.5.5 Enable (F4) Begins transmissions, if in stream mode. 6.1.5.6 Set Sampling Rate (F3, XX) In the stream mode, this command set the sampling rate to the value indicated by byte hex XX, shown in following:
Second byte XX 0A 14 28 3c 50 64 C9 Sample Rate 10/sec 20/sec 40/sec 60/sec 80/sec 100/sec 200/sec
6.1.5.7 Read Device Type (F2) EKM6211 always echoes " FA, 00" following this command. 6.1.5.8 Set Remote Mode (F0) Data values are reported only in response to a Read Data command. 6.1.5.9 Set Wrap Mode (EE) Wrap mode remains until Reset (FF) or Reset Wrap Mode (EC) is received. 6.1.5.10 Reset Wrap Mode (EC) EKM6211 returns to the previous mode of operation after receiving this command.

EKM6211 RF Mouse Rx Controller 6.1.5.11 Read Data (EB) This command is executed in either remote or stream mode. The data is transmitted even if there has been no movement since the last report or the button status is unchanged. Following a Read Data command, the registers are cleared after a data transmission. 6.1.5.12 Set Stream Mode (EA) This command sets EKM6211 in stream mode. 6.1.5.13 Status Request (E9) When this command is issued by the system, EKM6211 responds with a 3-byte status report as follows:
Byte 1 Bit 0 1 2 3 4 5 6 7 2 3 0-7 0-7 Description 1 = Right button pressed 1 = Middle button pressed 1 = Left button pressed Reserved 0 = Normal speed, 1 = Auto-speed 0 = Disabled, 1 = Enabled 0 = Stream mode, 1 = Remote mode Reserved Current resolution setting (D0 - D7) Current sampling rate (D0 - D7)
6.1.5.14 Set Resolution (E8, XX) EKM6211 provides four resolutions selected by the second byte of this command as follows:
Second Byte XX 00 01 02 03 Resolution 8 dot/count 4 dot/count 2 dot/count 1 dot/count
6.1.5.15 Set Auto-speed (E7) At the end of a sample interval in the stream mode, the current X and Y data values are converted new values. The sign bits are not involved in this conversion. The conversion is only in stream mode. The relationship between the input and output count follows:
