4704 Keyboard Protocol
|
||||
======================
|
||||
On powering up the keyboard sends keyboard id; A3h for 6019284(62-key), for example.
|
||||
After that firmware 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).
