Reserved.

4

LOGIC_INT

Read/write

0 = no interrupt.

1 = interrupt due to a general logic condition.

3

N/A

Reserved.

2

OVERFLOW_INT

Read/write

0 = no interrupt.

1 = interrupt due to an overflow condition.

1

GPI_INT

Read/write

This bit is not set by a GPI that has been configured to update the FIFO and event count.

This bit cannot be cleared until all GPI_x_INT bits are cleared.

0 = no interrupt.

1 = interrupt due to a general GPI condition.

0

EVENT_INT

Read/write

0 = no interrupt.

1 = interrupt due to key event (press/release), GPI event (GPI programmed for FIFO

updates), or logic event (programmed for FIFO updates).

1

Interrupt bits are cleared by writing a 1 to the flag; writing a 0 or reading the flag has no effect.

Status Register 0x02

EVENT1_STATE

Read only

This bit represents the state of the event that is recorded in the EVENT1_IDENTIFIER[6:0] bit.

For key events from Event 1 to Event 36, use the following settings:

1 = key is pressed.

0 = key is released.

For GPI and logic events from Event 37 to Event 48, use the following settings:

1 = GPI/logic is active.

0 = GPI/logic is inactive.

Active and inactive states for Event 37 to Event 48 are programmable.

6 to 0

EVENT1_IDENTIFIER[6:0]

Read only

Contains the event identifier for the pin. Refer to Table 11.
