Function Descriptions
Keyboard Buffer
keyboard will buffer bytes first-in-first-out order when system able receive scan codes from keyboard. response codes repeated codes will buffered. keystrokes generate multiple-byte sequence, entire sequence must into buffer keystroke discarded buffer-overrun condition occurs.
Power-on Reset Self Test
duration keyboard Power-on-Reset(POR) should within milliseconds seconds after power applied keyboard. After executing keyboard executes self test. LEDs turned beginning self test. self test takes minimum milliseconds maximum milliseconds. self test successful, completion code sent system keyboard starts scanning. self test fails, error code sent, keyboard disabled waits command from system. completion codes sent between milliseconds seconds after POR, between milliseconds after RESET command acknowledged.
Keyboard Data Output
When keyboard ready send data system, first checks clock data lines. either state, data stored keyboard buffer. both high state, keyboard starts clocking data out. Data will valid before trailing edge after leading edge clock pulse. During transmission keyboard checks clock line least every microseconds system lowers
Product Specification (V1.0) 03.28.2003
(This specification subject change without further notice)
EM83053DH Micro-controller clock lines before leading edge 10th clock, keyboard should stop sending, then buffer data return clock data lines high state.
Keyboard Data Input
When system ready send data keyboard, first checks clock line keyboard sending data. keyboard sending data sending data reached 10th clock, system inhibit interface forcing clock line more than microseconds prepares send data. keyboard checks clock line status least every milliseconds. system Request Send(RTS) detected, keyboard clocks bits After 10th bit, keyboard checks high state data line then pulls clocks more signal system that data been received. data after 10th bit, indicates frame error. keyboard should continue count until data line goes high, then pulls issues RESEND system.
Command from System
system send commands keyboard time. keyboard needs respond within milliseconds, unless system prevents keyboard output, when doing self test executing RESET. following keyboard input commands actions that keyboard needs take. /Reset Status indicators Responds ACK. Receives option byte. Responds ACK. Updates status indicators. Returns previous scanning state.
Echo Responds with hex. Returns previous scanning state.
Invalid commands Returns RESEND command. Returns previous scanning state.

EM83053DH Micro-controller Select Alternate Scan Codes Responds ACK. Clears output buffer. Sets default typematic rate/delay. Clears last typematic key. Receives option byte. Responds ACK. Option byte selects scan code selects scan code selects scan code Returns previous scanning rate.
Read (F2) Responds with ACK. Discontinues scanning. Sends bytes. second byte will sent within after first byte. Resumes scanning.
Typematic Rate/Delay Responds ACK. Receives rate/delay value byte Responds ACK. rate/delay Note Returns previous scanning state.

Command System
following keyboard output commands. Acknowledge keyboard sends acknowledge response valid command from system except RESEND ECHO.
Completion Code This command issued after successful completion keyboard self test.
Echo keyboard sends this code response ECHO command.
Keyboards 83AB byte issued respond READ command. byte sent first, followed high byte. Keyboard buffer Overrun keyboard buffer overflows, overrun code will replace last byte buffer. keyboard using scan code code sets code

EM83053DH Micro-controller Resend When keyboard receives invalid input input with incorrect parity, RESEND command sent.
Keyboard Scan Code Table
keyboard contains scan code sets. system defaults scan code switched following tables show numbers three scan code sets hexadecimal values. keys typematics except pause key. When pressed down, make scan code sent system. When released, break code sent. more keys held down, only last pressed repeats typematic rate. Typematic operation stops when last pressed released, even other keys being released some other keys still held down.
