Description

AUTO_INC

7

GPIEM_CFG

6

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.

OVR_FLOW_M

5

Overflow mode.

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.

INT_CFG

4

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.

OVR_FLOW_IEN

3

Overflow interrupt enable.

1: Overflow interrupt is enabled.

0: Overflow interrupt is disabled.

K_LCK_IM

2

Keypad lock interrupt mask.

1: Keypad lock interrupt is enabled.

0: Keypad lock interrupt is disabled.

GPI_IEN

1

GPI interrupt enable.

1: GPI interrupt is enabled.

0: GPI interrupt is disabled.

KE_IEN

0

Key events interrupt enable.

1: Key events interrupt is enabled.

0: Key events interrupt is disabled.
