Function Description
This section divided into subsections user convenience clearer distinction. Detailed PS/2 keyboard function descriptions provided Section 6.1. keyboard function descriptions discussed details Section 6.2.
PS/2 Keyboard Function Description
keyboard buffer, power-on reset self test, input, output, commands, scan codes described following sections.
6.1.1 Keyboard Buffer
keyboard will buffer bytes first-in-first-out order when system receives 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.
6.1.2 Power-on Reset Self Test
duration keyboard Power-on-Reset (POR) should within milliseconds seconds after power applied keyboard. After executing POR, 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 after POR, between after reset command acknowledged.
6.1.3 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 valid before trailing edge after leading edge clock pulse. During transmission, keyboard checks clock line least every microseconds. system lowers clock lines before leading edge 10th clock, keyboard should stop sending, then buffers data return clock data lines high state.

6.1.4 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.
6.1.5 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 (Hex Responds with Receives option byte Responds with Updates status indicators Returns previous scanning state Echo (Hex EEH) Responds with Returns previous scanning state Invalid commands (Hex Returns RESEND command Returns previous scanning state Select Alternate Scan Codes (Hex Responds Clears output buffer Sets default Typematic rate/delay Clears last Typematic Receives option byte Responds Option byte selects scan code selects scan code selects scan code Returns previous scanning rate
