-IBM 4704 to USB keyboard converter
-==================================
-This firmware converts IBM 4704 keyboard protocol to USB HID.
-
-Keyboard initialization process takes a few seconds at start up. During that you will hear buzzer from the keyboard. **You need to plug USB cable after hooking up your keyboard to the converter.**

-
-Connection
-----------
-In case of using ATMega32U4(Teensy2.0):
-
-1. Supply power with VCC and GND.
-2. Connect CLOCK to PD1 and DATA to PD0. You can change pin with config.h.
-3. Optionally you may need pull-up register. 1KOhm probably work.
-
-
-Build Firmware
---------------
-Just run `make`:
-
-    $ make
-
-To select keymap:
-
-    $ make KEYMAP=[plain|...]
-
-
-Keymap
-------
-Several version of keymap are available in advance but you are recommended to define your favorite layout yourself. To define your own keymap create file named `keymap_<name>.c` and see keymap document(you can find in top README.md) and existent keymap files.
-
-Use `KEYMAP_ALPS102()` to define your keymap for Alps models.

-IBM 4704 Keyboard Protocol
-==========================
-On powering up keyboard sends keyboard ID; A3h for 6019284(62-key), for example.
-After that the keyboard enters FC command mode and waits for parameter data from host
-so that it doesn't send any scancode until you send 'FF'(End of FC command mode).

-            After request host release Clock line once Data line becomes hi.
-            Host wirtes a bit while Clock is hi and Keyboard reads while low.

-    Bit7 is 'press flag' which set 1 on press and 0 on release when break code is enabled.

-NOTE: When break code is enabled the key sends scancode with setting 7th bit on press
-and without it on release. That is, '`' sends 80h on press and 00h on release.

-    
-
-Keyboard response
------------------
-Keyobard sends these bytes to host.
-
-        Description                             Entry point
-    -----------------------------------------------------------
-    FE  Overflow(key event/receive data)        00c5h, 0346h
-        Memory test error                       0224h
-    FD  Command out of bound                    00d8h
-        Key out of bound
-    7E  Read/Parity error in receive from host  00bch
-
-
-Set Key Flag command(FC)
-------------------------
-After 'Power on Reset' firmware enters this command mode and waits for data from host,
-so that you don't need to send 'FC' and it doesn't send any scancode until you send 'FF'.
-
-Data sent from host:
-
-    bit: 7   6 ... 0
-         en  |     |
-         |   `-----`--- scan code
-         `------------- enable bit(0: enable repeat, 1: enable break)
-
-    00-79   Enable repeat
-    80-F9   Enable break(FA-FF are used as other commands, see above.)
-    FE      Resend(011ah) no need to use
-    FF      End(0114h) exits FC command mode.
-
-Response from keyboard:
-    FD      Out of bound - Invalid scancode
-    --      OK - No response means that command is accepted.
-
-Examples:
-    To enable break code of all keys.
-
-    FC 80 81 ... F7 FF
