Description
Reserved.
0 = no interrupt.
1 = interrupt due to a general logic condition.
Reserved.
0 = no interrupt.
1 = interrupt due to an overflow condition.
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 = no interrupt.
1 = interrupt due to key event (press/release), GPI event (GPI programmed for FIFO
updates), or logic event (programmed for FIFO updates).
Description
Reserved.
0 = output from logic block (LY) is low.
1 = output from logic block (LY) is high.
Reserved.
Event count value. Indicates how many events are currently stored on the FIFO.
Description
This bit represents the state of the event that is recorded in the EVENT1_IDENTIFIER[6:0] bits.
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.
Contains the event identifier for the pin. See Table 12 for event decoding information.
