Keyboard Scan Code
This register is used to decode the first byte received from keyboards that
generate multi-byte make codes and for single byte make codes.
Bit[0] LSB of Scan Code
Bit[7] MSB of Scan Code
Note: The keyboard scan code registers default to the ACPI scan 2 Power
make/break codes.
(i.e., make=E0_37, break=E0_F0_37).
Note: Programming this register to 0x00 indicates that this register a don’t
care. Any valid scan code that is received will be a match.
