Description
Defines which state the first unlock event should be
For key events:
0 = not applicable; releases not used for unlock.
1 = press is used as unlock event.
For GPIs and logic outputs configured for FIFO updates:
0 = inactive event used as reset condition.
1 = active event used as reset condition.
Defines the first event that must be detected to unlock the keypad after LOCK_EN has been set.
Description
