* Size of Bootloaders in bytes:
* Atmel DFU loader(ATmega32U4) 4096

* LUFA bootloader(ATmega32U4) 4096

* Teensy halfKay(ATmega32U4) 512
* Teensy++ halfKay(AT90USB128) 1024
*
* AVR Boot section is located at the end of Flash memory like the followings.

* We emulate eeprom by writing a snapshot compacted view of eeprom contents,
* followed by a write log of any change since that snapshot:
*
* === SIMULATED EEPROM CONTENTS ===
*
* ┌─ Compacted ┬ Write Log ─┐
* │............│[BYTE][BYTE]│
* │FFFF....FFFF│[WRD0][WRD1]│

* │....FFFFFFFF│[BYTE][WRD0]│
* ├────────────┼────────────┤
* └──PAGE_BASE │ │
* PAGE_LAST─┴─WRITE_BASE │
* WRITE_LAST ┘
*
* Compacted contents are the 1's complement of the actual EEPROM contents.
* e.g. An 'FFFF' represents a '0000' value.
*
* The size of the 'compacted' area is equal to the size of the 'emulated' eeprom.
* The size of the compacted-area and write log are configurable, and the combined
* size of Compacted + WriteLog is a multiple FEE_PAGE_SIZE, which is MCU dependent.
* Simulated Eeprom contents are located at the end of available flash space.
*
* The following configuration defines can be set:
*
* FEE_PAGE_COUNT # Total number of pages to use for eeprom simulation (Compact + Write log)
* FEE_DENSITY_BYTES # Size of simulated eeprom. (Defaults to half the space allocated by FEE_PAGE_COUNT)
* NOTE: The current implementation does not include page swapping,
* and FEE_DENSITY_BYTES will consume that amount of RAM as a cached view of actual EEPROM contents.
*
* The maximum size of FEE_DENSITY_BYTES is currently 16384. The write log size equals
* FEE_PAGE_COUNT * FEE_PAGE_SIZE - FEE_DENSITY_BYTES.
* The larger the write log, the less frequently the compacted area needs to be rewritten.
*
*
* *** General Algorithm ***
*
* During initialization:
* The contents of the Compacted-flash area are loaded and the 1's complement value
* is cached into memory (e.g. 0xFFFF in Flash represents 0x0000 in cache).
* Write log entries are processed until a 0xFFFF is reached.
* Each log entry updates a byte or word in the cache.
*
* During reads:
* EEPROM contents are given back directly from the cache in memory.
*
* During writes:
* The contents of the cache is updated first.
* If the Compacted-flash area corresponding to the write address is unprogrammed, the 1's complement of the value is written directly into Compacted-flash
* Otherwise:
* If the write log is full, erase both the Compacted-flash area and the Write log, then write cached contents to the Compacted-flash area.
* Otherwise a Write log entry is constructed and appended to the next free position in the Write log.
*
*
* *** Write Log Structure ***
*
* Write log entries allow for optimized byte writes to addresses below 128. Writing 0 or 1 words are also optimized when word-aligned.

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:

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.

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