-
-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.
-
-    Signaling:

-    ~~~~____________~~||||||||||||__~~~~~_~~|||||||||||||||__~~~~

-    bit0: ______~~~
-          65    :35us
-
-    bit1: ___~~~~~~
-          35 :65us
-
-    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.

-     | +-+-+-+-+-+-+-----------------   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.
