MX83093
USB+PS/2 Keyboard Encoder
5.1 PS/2 KEYBOARD FUNCTION DESCRIPTION
The keyboard buffer, power-on reset and self test, input, output, commands, and scan codes are
described in the following sections.
5.1.1 KEYBOARD BUFFER
The keyboard will buffer 16 bytes in a first-in-first-out order when the system receives scan codes
from the keyboard. The response codes and repeated codes will not be buffered. If the 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.
5.1.2 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 of 300 milliseconds and a
maximum of 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 ms to 2.5 s after POR, and between 300 ms to 500 ms after a reset command is
acknowledged.
5.1.3 LOW VOLTAGE RESET (LVR)
MX83093 has a low voltage reset function, which is used to monitor the voltage of power supply or
external source. The low voltage reset voltage is 3.0V3.2V. Vhys > 0.1V. Low voltage reset will
not happen if the period Vdd stays in low voltage is less than T ( 0.6ms).
