+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 Request(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.

+ [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.
