-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 ~~~~~~~~~~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~|__|~~~~~~~~~~~

- <--> 160us(clock low)
- <---> 180us(clock high)
-
-3) HOST->KEYBOARD: HOST asserts bit on falling edge.

-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
