4.22 Cal Key ‘k’ - 0xck
This command must be repeated 2x within 100ms or the
command will fail; the repeating command must be sequential
without any intervening command.
This command functions the same as 0x03 CAL command
except this command only affects one key ‘k’ where ‘k’ is from
0 to 47.

The chosen key ‘k’ is recalibrated in its native timeslot; normal
running of the part is not interrupted and all other keys
operate correctly throughout. This command is for use only
during normal operation to try to recover a single key that has
failed or is not calibrated correctly.
Returns the 1’s compliment of 0xck just before the key is
recalibrated.
