Commands
--------
ADB command is 1byte and consists of 4bit-address, 2bit-command
type and 2bit-register. The commands are always sent by Host.
Command format:
7 6 5 4 3 2 1 0
| | | |------------ address
| |-------- command type
| |---- register
bits commands
------------------------------------------------------
- - - - 0 0 0 0 Send Reset(reset all devices)
A A A A 0 0 0 1 Flush(reset a device)
- - - - 0 0 1 0 Reserved
- - - - 0 0 1 1 Reserved
- - - - 0 1 - - Reserved
A A A A 1 0 R R Listen(write to a device)
A A A A 1 1 R R Talk(read from a device)
The command to read keycodes from keyboard is 0x2C which
consist of keyboard address 2 and Talk against register 0.
Address:
2: keyboard
3: mice
Registers:
0: application(keyboard uses this to store its data.)
1: application
2: application(keyboard uses this for LEDs and state of modifiers)
3: status and command
Communication
-------------
This is a minimum information for keyboard communication.
See "Resources" for detail.

Bit cells:

bit0 low time: 60-70% of bit cell(42-91us)
bit1 low time: 30-40% of bit cell(21-52us)
bit cell time: 70-130us
[from Apple IIgs Hardware Reference Second Edition]
Criterion for bit0/1:
After 55us if line is low/high then bit is 0/1.
Attention & start bit:
Host asserts low in 560-1040us then places start bit(1).
Tlt(Stop to Start):
Bus stays high in 140-260us then device places start bit(1).
Global reset:
Host asserts low in 2.8-5.2ms. All devices are forced to reset.
Service request from device(Srq):
Device can request to send at commad(Global only?) stop bit.
Requesting device keeps low for 140-260us at stop bit of command.
Keyboard Data(Register0)
This 16bit data can contains two keycodes and two released flags.
First keycode is palced in upper byte. When one keyocode is sent,
lower byte is 0xFF.
Release flag is 1 when key is released.

| | | | | | | | +--------------- Released2(1 when the key is released)
| +-+-+-+-+-+-+----------------- Keycode1
+------------------------------- Released1(1 when the key is released)
Keycodes:
Scancode consists of 7bit keycode and 1bit release flag.
Device can send two keycodes at once. If just one keycode is sent
keycode1 contains it and keyocode2 is 0xFF.
Power switch:
You can read the state from PSW line(active low) however
the switch has a special scancode 0x7F7F, so you can
also read from Data line. It uses 0xFFFF for release scancode.
Keyboard LEDs & state of keys(Register2)
This register hold current state of three LEDs and nine keys.
The state of LEDs can be changed by sending Listen command.

Primitive M0110 Library for AVR
==============================
Signaling
---------
CLOCK is always from KEYBOARD. DATA are sent with MSB first.
1) IDLE: both lines are high.
CLOCK ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
DATA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
2) KEYBOARD->HOST: HOST reads bit on rising edge.
CLOCK ~~~~~~~~~~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~~~~~~~~~
DATA ~~~~~~~~~~~~X777777X666666X555555X444444X333333X222222X111111X000000X~~~~~~~
<--> 160us(clock low)
<---> 180us(clock high)
3) HOST->KEYBOARD: HOST asserts bit on falling edge.
CLOCK ~~~~~~~~~~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~~~~~~~~~
DATA ~~~~~~|_____X777777X666666X555555X444444X333333X222222X111111X000000X~~~~~~~
<----> 840us(request to send by host) <---> 80us(hold DATA)
<--> 180us(clock low)
<---> 220us(clock high)
Protocol
--------
COMMAND:
Inquiry 0x10 get key event with block
Instant 0x12 get key event
Model 0x14 get model number(M0110 responds with 0x09)
bit 7 1 if another device connected(used when keypad exists?)
bit4-6 next device model number
bit1-3 keyboard model number
bit 0 always 1
Test 0x16 test(ACK:0x7D/NAK:0x77)
KEY EVENT:
bit 7 key state(0:press 1:release)
bit 6-1 scan code(see below)
bit 0 always 1
To get scan code use this: ((bits&(1<<7)) | ((bits&0x7F))>>1).
Note: On the M0110A, Keypad keys and Arrow keys are preceded by 0x79.
Moreover, some Keypad keys(=, /, * and +) are preceded by 0x71 on press and 0xF1 on release.
ARROW KEYS:
Arrow keys and Calc keys(+,*,/,= on keypad) share same byte sequence and preceding byte of
Calc keys(0x71 and 0xF1) means press and release event of SHIFT. This causes a very confusing situation,
it is difficult or impossible to tell Calc key from Arrow key plus SHIFT in some cases.
Raw key events:
press release
