After releasing KCLK, the keyboard jumps to its start-up code (internal RESET). This will
initialize the keyboard in the same way as cold power-on.
NOTE
The keyboard must resend the "powerup key stream"!
SPECIAL CODES
The special codes that the keyboard uses to communicate with the main unit are
summarized here.
NOTE
The special codes are 8-bit numbers; there is no up/down flag associated with them.
However, the transmission bit order is the same as previously described.
