In section 6.2, we provide the USB keyboard function descriptions. 6.1 PS/2 Keyboard Function Description We describe the keyboard buffer, power-on Reset and self test, input, output, command, and scan codes in the following sections. 6.1.1 Keyboard Buffer The keyboard will buffer 16 bytes in a first-in-first-out order when the system is able to receive scan codes from the keyboard. The response codes and repeated codes will not be buffered. If keystrokes generate a multiple-byte sequence, the entire sequence must fit into the buffer or the keystroke is discarded and a buffer-overrun condition occurs. 6.1.2 Power-on Reset and Self Test The duration of the keyboard Power-on-Reset(POR) should be within 150 milliseconds and 2 seconds after the power is applied to the keyboard. After executing POR , the keyboard executes a self test. The LEDs are turned on at the beginning and off at the end of the self test. The self test takes a minimum 300 milliseconds and a maximum 500 milliseconds. If the self test is successful, a completion code AA hex is sent to the system and the keyboard starts scanning. If the self test fails, and error code is sent, the keyboard is disabled and waits for a command from the system. The completion codes are sent between 450 milliseconds and 2.5 seconds after POR, and between 300 and 500 milliseconds after a RESET command is acknowledged. 6.1.3 Keyboard Data Output When the keyboard is ready to send data to the system, it first checks clock and data lines. If either one is in the low state, data is stored in the keyboard buffer. If both are in the high state, keyboard starts clocking data out. Data will be valid before the trailing edge and after the leading edge of the clock pulse. During the transmission the keyboard checks the clock line at least every 60 microseconds . If the system lowers the clock lines before the leading edge of the 10th clock, the keyboard should stop sending, then buffer the data and return clock and data lines to high state. 6.1.4 Keyboard Data Input When the system is ready to send data to the keyboard, it first checks clock line to see if keyboard is sending data. If keyboard is not sending data or it is sending data but has not reached the 10th clock, the system can inhibit the interface by forcing the clock line low for more than 60 microseconds and prepares to send data. The 4* Product Specification (V1.0) 06.10.2003 (This specification is subject to change without further notice) EKK8011 USB & PS/2 Keyboard Encoder keyboard checks clock line status at least every 5 milliseconds. If a system Request to Send(RTS) is detected, the keyboard clocks 11 bits in. After the 10th bit, the keyboard checks for a high state in data line then pulls it low and clocks one more bit to signal the system that data has been received. If data is low after the 10th bit, it indicates a frame error. The keyboard should continue to count until data line goes high, then pulls it low and issues a RESEND to the system. 6.1.5 Command from the System The system can send commands to the keyboard at any time. The keyboard needs to respond within 20 milliseconds, unless the system prevents keyboard output, when doing self test or executing a RESET. The following are the keyboard input commands and the actions that keyboard needs to take. Set /Reset Status indicators ( Hex ED ) - Responds ACK. - Receives option byte. - Responds ACK. - Updates status indicators. - Returns to previous scanning state. Echo ( Hex EEH ) - Responds with EE hex. - Returns to previous scanning state. Invalid commands ( Hex EF and F1 ) - Returns a RESEND command. - Returns to previous scanning state. Select Alternate Scan Codes ( Hex F0 ) - Responds ACK. - Clears output buffer. - Sets the default typematic rate/delay. - Clears last typematic key. - Receives option byte. Product Specification (V1.0) 06.10.2003 (This specification is subject to change without further notice) 5 EKK8011 USB & PS/2 Keyboard Encoder - Responds ACK. - Option byte = 01 : selects scan code set 1 02 : selects scan code set 2 03 : selects scan code set 3 - Returns to previous scanning rate. Read ID (F2) - Responds with ACK. - Discontinues scanning. - Sends two ID bytes. The second byte will be sent within 500 uS after first byte. - Resumes scanning. Set Typematic Rate/Delay ( Hex F3 ) - Responds ACK. - Receives rate/delay value byte - Responds ACK. - Set rate/delay (* Note 1) - Returns to previous scanning state. * Note 1 1.

Acknowledge ( Hex FA ) The keyboard sends an acknowledge in response to any valid command from the system except for RESEND and ECHO. BAT Completion Code ( Hex AA ) This command is issued after successful completion of keyboard self test. Echo ( Hex EE ) The keyboard sends this code in response to an ECHO command. Keyboards ID ( Hex 83AB ) The 2 byte ID is issued to respond to READ ID command. The low byte is sent first, followed by the high byte. Keyboard buffer Overrun ( Hex 00 or FF ) If keyboard buffer overflows, the overrun code will replace the last byte in the buffer. If the keyboard is using scan code set 1 , the code is hex FF. For sets 2 and 3, the code is hex 00. Resend ( Hex FE ) When the keyboard receives an invalid input or any input with incorrect parity, the RESEND command is sent. 6.1.7 Keyboard Scan Code Table The keyboard contains 3 scan code sets. The system defaults to scan code set 2, but can be switched to set 1 or set 3 . The following tables show the key numbers and three scan code sets in hexadecimal values. All the keys are typematics except for the pause key. When a key is pressed down, the make scan code is sent to the system. When the key is released, its break code is sent. If two or more keys are held down, only the last key pressed repeats at the typematic rate. Typematic operation stops when the last pressed key is released, even if other keys are being released or some other keys are still held down.
