Copam K-430 is an AT/XT Auto-Switching keyboard with "AA with parity error" method.
https://geekhack.org/index.php?topic=111510.msg3086764#msg3086764

TMK IBMPC converter recognizes it as a XT keyboard because the converter doesn't detect and recover parity error.

Deteciting parity error to send command(FE or FF) is need to communicate with the keyboard on AT protocol.
In general AT protocol is preferable to XT for keyboard functionality.
It would be useful for debug purpose if user can select protocol by some way or other.

"AA with parity error" method:
