-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.

-
-    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.

-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~~~~~~~

-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
-            ----------------    ----------------
-    Left:         0x79, 0x0D          0x79, 0x8D
-    Right:        0x79, 0x05          0x79, 0x85
-    Up:           0x79, 0x1B          0x79, 0x9B
-    Down:         0x79, 0x11          0x79, 0x91
-    Pad+:   0x71, 0x79, 0x0D    0xF1, 0x79, 0x8D
-    Pad*:   0x71, 0x79, 0x05    0xF1, 0x79, 0x85
-    Pad/:   0x71, 0x79, 0x1B    0xF1, 0x79, 0x9B
