0: Pin is unlocked. The corresponding bit can be changed in any GPIO register for this port.
1: Pin is locked. The corresponding bit can not be changed in any GPIO register for this port.
The value of LOCK determines which bits are locked in the lockable registers.
The LOCK, LOCKC, and LOCKT registers are protected, which means they can only be written immediately after a write to the
UNLOCK register with the proper KEY and OFFSET.
LOCKS is not protected, and can be written at any time.
