||||

|
||||
Linux source code
|
||||
Test hardware:
|
||||
New Samsung KB3T001SAXAA 104-key keyboard
|
||||
Old Maxi 2186035-00-21 101-key keyboard
|
||||
|
||||
NO WARRANTY. NO GUARANTEE. I have tried to make this information
|
||||
accurate. I don't know if I succeeded. Corrections or additional
|
||||
information would be welcome.
|
||||
|
||||
This is a plain-text document. If you use a word-processor to view
|
||||
it, use a fixed-pitch font (like Courier) so columnar data and
|
||||
ASCII art lines up properly.
|
||||
|
||||
Lessons learned:
|
||||
- Both the 8048 MCU in the keyboard and the 8042 controller
|
||||
on the motherboard accept command bytes.
|
||||
- There is a bit (KCC) in the poorly-named "Command Byte" which
|
||||
seems to enable AT-to-XT scancode conversion (scancode set 2
|
||||
to scancode set 1). After booting DOS, my keyboard uses
|
||||
scancode set 2 with this conversion bit turned on. If I turn
|
||||
the bit off and switch to scancode set 1, operation remains
|
||||
the same.
|
||||
- Scancode set 3 is probably the most elegant, in that it returns
|
||||
a one-byte make code for _every_ key. Unfortunately, not all
|
||||
keyboards support it.
|
||||
- The scancodes of some keys depend on the internal num lock state
|
||||
of the keyboard.

|

|
||||
|
||||
================================================================
|
||||
CONTROLLER COMMANDS (from Table P0401 of PORTS.A)
|
||||
================================================================
|
||||
Before writing each byte of these commands to port 64h,
|
||||
poll the status register (port 60h) until bit b1=0.
|
||||
|
||||
20h-2Fh reads byte with address=lower 5 bits of command
|
||||
The byte at address 0 is the "Command Byte".
|
||||
60h-7Fh nn writes byte nn to address=lower 5 bits of command
|
||||
The byte at address 0 is the "Command Byte".
|
||||
A7h disables PS/2 mouse port (MCA only?)
|
||||
A8h enables PS/2 mouse port (MCA only?)
|
||||
A9h self-test mouse interface, returns Result Byte (see above)
|
||||
AAh self-test controller; returns 55h if success, FCh if failure
|
||||
ABh self-test keyboard interface, returns Result Byte (see above)
|
||||
ADh disables keyboard (sets b4 of "Command Byte")
|
||||
AEh enables keyboard (clears b4 of "Command Byte")
|
||||
C0h reads Input Port
|
||||
D0h reads Output Port
|
||||
D1h nn writes Output Port
|
||||
Important: bit 0 (system reset) should always be set here,
|
||||
as the system may hang constantly. To reset the PC, pulse
|
||||
b0 of the Output Port with command FEh instead.
|
||||
DDh disable A20 (Not all systems support this byte)
|
||||
DFh enable A20 (Not all systems support this byte)
|
||||
E0h read test inputs. return value=
|
||||
b1 kbd data
|
||||
b0 kbd clock
|
||||
EDh nn write LEDs. nn=
|
||||
b2 Caps Lock
|
||||
b1 Num Lock
|
||||
b0 Scroll Lock
|
||||
F0h-FFh pulse bit(s) of Output Port low for 6 microseconds.
|
||||
If b0-b3 of the command is low, the corresponding bit
|
||||
in the Output Port will be pulsed low. b0=system reset,
|
||||
and should ALWAYS be PULSED low, never set low constantly.
|
||||
|
||||
================================================================
|
||||
KEYBOARD COMMANDS (from Table P0386 of PORTS.A)
|
||||
================================================================
|
||||
Before writing each byte of these commands to port 60h,
|
||||
poll the status register (port 60h) until bit b1=0.
|
||||
Unless otherwise noted: each command responds with FAh (ACKnowledge)
|
||||
or FEh (Resend) after receiving each byte of the command.
|
||||
|
||||
EDh nn write LEDs, as above
|
||||
EEh echo, keyboard responds with EEh
|
||||
EFh no-operation (reserved)
|
||||
F0h nn selects scancode set nn=1-3 or 0 to return current set
|
||||
F2h read ID. Keyboard responds with ACK (FAh) and two optional
|
||||
ID bytes:
|
||||
(none) AT keyboard
|
||||
83h ABh (?)
|
||||
ABh 41h MF2, translation mode
|
||||
ABh 83h MF2, pass-through mode
|
||||
F3h nn set typematic (auto-repeat) rate/delay. nn=
|
||||
b7 unused
|
||||
b6..5 Repeat delay (00=250 msec ... 11=1000msec)
|
||||
b4..0 Repeat rate (00000=30 Hz ... 11111=2 Hz).
|
||||
F4h clears output buffer, enables keyboard
|
||||
F5h disables keyboard, resets to defaults
|
||||
F6h sets keyboard defaults
|
||||
|
||||
F7h make all keys typematic (auto-repeat) [*]
|
||||
F8h make all keys make-break [*]
|
||||
F9h make all keys make-only [*]
|
||||
FAh make all keys typematic and make-break [*]
|
||||
FBh nn make one key typematic [*]
|
||||
FCh nn make one key make-break [*]
|
||||
FDh nn make one key make-only [*]
|
||||
[*] these commands may work only for
|
||||
scancode set 3; I'm not sure.
|
||||
FEh resend previous scan code
|
||||
FFh reset keyboard CPU, do power-on self-test, return
|
||||
self-test result byte
|
||||
|
||||
non-key status bytes
|
||||
--------------------
|
||||
00h Key detection error or buffer full.
|
||||
AAh Power-on/reset diagnostics successful.
|
||||
E0h (scancode sets 1 and 2) Prefix byte for "gray" keys
|
||||
(keys not on original 83-/84-key keyboard)
|
||||
EEh Sent in response to ECHO command.
|
||||
F0h (scancode sets 2 and 3) Prefix byte for break codes.
|
||||
FAh ACKknowledge; response to most commands.
|
||||
FCh Diagnostics failed (MF keyboard).
|
||||
FDh Diagnostics failed (AT keyboard).
|
||||
The keyboard stops scanning and waits for next command
|
||||
after returning code FCh or FDh
|
||||
FEh Last command was invalid or had parity error; resend it.
|
||||
FFh Key detection error or buffer full.

SCANCODES FOR SCANCODE SET 1 (XT)
|
||||
====================================================================
|
||||
US 104-key keyboard, set 1 scancodes
|
||||
|
||||
|
||||
"Make" code is generated when key is pressed.
|
||||
"Break" code is generated when key is released.
|
||||
Hex value of make code for each key is shown.
|
||||
|
||||
Most keys:
|
||||
one-byte make code = nn
|
||||
one-byte repeat code = nn
|
||||
one-byte break code = 80h + nn
|
||||
|
||||
"Gray" keys (not on original 84-key keyboard):
|
||||
two-byte make code = E0nn
|
||||
two-byte repeat code = E0nn
|
||||
two-byte break code = E0 followed by 80h + nn
|
||||
|
||||
"Gray" keys noted by [1] are NumLock-sensitive.
|
||||
When the keyboard's internal NumLock is active:
|
||||
four-byte make code = E02AE0nn
|
||||
two-byte repeat code = E0nn
|
||||
four-byte break code = E0 followed by 80h + nn followed by E0AA
