MX83063B
USB/U+P Keyboard Encoder
This section is divided into subsections for user convenience and clearer distinction.
Detailed PS/2 keyboard function descriptions are provided in Section 5.1. The USB keyboard
function descriptions are discussed in details in Section 5.2.
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)
MX83063B 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 3.0V－3.2V.
Vhys > 0.1V. Low voltage reset will not happen if the period Vdd stays in low voltage is
less than T ( 0.6ms).
