Description

7

GPI_8_EVENT_EN

R/W

0 = disable GPI events.

1 = allow GPI 8 activity to generate events on the FIFO.

6

GPI_7_EVENT_EN

R/W

0 = disable GPI events.

1 = allow GPI 7 activity to generate events on the FIFO.

5

GPI_6_EVENT_EN

R/W

0 = disable GPI events.

1 = allow GPI 6 activity to generate events on the FIFO.

4

GPI_5_EVENT_EN

R/W

0 = disable GPI events.

1 = allow GPI 5 activity to generate events on the FIFO.

3

GPI_4_EVENT_EN

R/W

0 = disable GPI events.

1 = allow GPI 4 activity to generate events on the FIFO.

2

GPI_3_EVENT_EN

R/W

0 = disable GPI events.

1 = allow GPI 3 activity to generate events on the FIFO.

1

GPI_2_EVENT_EN

R/W

0 =disable GPI events.

1 = allow GPI 2 activity to generate events on the FIFO.

0

GPI_1_EVENT_EN

R/W

0 = disable GPI events.

1 = allow GPI 1 activity to generate events on the FIFO.

GPIs in this mode are considered FIFO events and can be used for unlock purposes.

GPI activity in this mode causes EVENT_INT interrupts.

GPIs in this mode do not generate GPI_INT interrupts.
