Overflow mode.
Overflow interrupt enable.
GPI interrupt enable.
Description
I
1: I
0: I
GPI event mode configuration.
1: GPI events are not tracked when the keypad is locked.
0: GPI events are tracked when the keypad is locked.
1: Overflow mode is on; register overflow data shifts in, starting at the last event and losing first event data.
0: Overflow mode is off; register overflow data is lost.
Interrupt configuration.
1: Processor interrupt deasserts for 50 μs and reasserts with pending key events.
0: Processor interrupt remains asserted when host tries to clear interrupt while there is a pending key event.
1: Overflow interrupt is enabled.
0: Overflow interrupt is disabled.
Keypad lock interrupt mask.
1: Keypad lock interrupt is enabled.
0: Keypad lock interrupt is disabled.
1: GPI interrupt is enabled.
0: GPI interrupt is disabled.
Key events interrupt enable.
1: Key events interrupt is enabled.
0: Key events interrupt is disabled.
