Register Descriptions
Port 64 - Keyboard / Mouse Command ......................... WO
This port is used to send commands to the keyboard / mouse
controller. The command codes recognized by the
VT82C586B are listed n the table below.
Note: The VT82C586B Keyboard Controller is compatible
with the VIA VT82C42 Industry-Standard Keyboard
Controller except that due to its integrated nature, many of the
input and output port pins are not available externally for use
as general purpose I/O pins (even though P13-P16 are set on
power-up as strapping options). In other words, many of the
commands below are provided and “work”, but otherwise
perform no useful function (e.g., commands that set P12-P17
high or low). Also note that setting P10-11, P22-23, P26-27,
and T0-1 high or low directly serves no useful purpose, since
these bits are used to implement the keyboard and mouse ports
and are directly controlled by keyboard controller logic.

Keyboard Command Code Description
Read input port (read P10-17 input data to
the output buffer)
Poll input port low (read input data on P11-13
repeatably & put in bits 5-7 of status
Poll input port high (same except P15-17)
C1h
C2h
C8h
Unblock P22-23 (use before D1 to change
active mode)
Reblock P22-23 (protection mechanism for D1)
C9h
CAh
Read mode (output KBC mode info to port 60
output buffer (bit-0=0 if ISA, 1 if PS/2)
D0h
Read Output Port (copy P10-17 output port values
to port 60)
Write Output Port (data byte following is written to
keyboard output port as if it came from keyboard)
Write Keyboard Output Buffer & clear status bit-5
(write following byte to keyboard)
Write Mouse Output Buffer & set status bit-5 (write
following byte to mouse; put value in mouse input
buffer so it appears to have come from the mouse)
Write Mouse (write following byte to mouse)
D1h
D2h
D3h
D4h
E0h
Exh
Fxh
Read test inputs (T0-1 read to bits 0-1 of resp byte)
Set P23-P21 per command bits 3-1
Pulse P23-P20 low for 6usec per command bits 3-0
All other codes not listed are undefined.
