------------------------
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'.
+With Alps models you need to send 'FC' command to enter this mode.
Data sent from host:
| `-----`--- scan code
`------------- enable bit(0: enable repeat, 1: enable break)
