Description
Reserved.
0 = no interrupt.
1 = interrupt due to a general Logic 2 condition.
Write a 1 to this bit to clear it.
0 = no interrupt.
1 = interrupt due to a general Logic 1 condition.
Write a 1 to this bit to clear it.
0 = no interrupt.
1 = interrupt due to a lock/unlock condition.
The user can read LOCK_STAT (0x02[5]) to determine if LOCK_INT is due to a lock or unlock event.
If LOCK_STAT = 1, LOCK_INT is due to a lock event.
If LOCK_STAT = 0, LOCK_INT is due to an unlock event.
Write a 1 to this bit to clear it.
If lock mode is enabled via the software bit LOCK_EN (0x37[0]), a LOCK_INT is not generated
because the processor knows it just enabled lock mode.
If lock mode is disabled (while locked) via the software bit LOCK_EN, a LOCK_INT is not generated
because the processor knows it just disabled lock mode.
0 = no interrupt.
1 = interrupt due to an overflow condition.
Write a 1 to this bit to clear it.
0 = no interrupt.
1 = interrupt due to a general GPI condition.
This bit is not set by a GPI that has been configured to update the FIFO and event count.
Write a 1 to this bit to clear it.
This bit cannot be cleared until all GPI_x_INT bits are cleared.
0 = no interrupt.
1 = interrupt due to key event (press/release), GPI event (GPI programmed for FIFO updates), or
Logic 1/Logic 2 event (programmed for FIFO updates).Write a 1 to this bit to clear it.
Description
0 = output from
1 = output from
0 = output from Logic Block 1 (LY1) is low.
1 = output from Logic Block 1 (LY1) is high.
0 = unlocked.
1 = locked.
Event count value. Indicates how many events are currently stored on the FIFO.
