Description
AUTO_INC
7
I2C autoincrement. Burst read is supported; burst write is not supported.
1: I2C autoincrement is on.
0: I2C autoincrement is off.
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
