Description
7
Event1_State
R
The seven lower bits of each FIFO location contain the event identifier, which can be
decoded to reveal the event recorded.
Table 11 outlines each event number, what it represents, and the I/O pins associated with it.
Bit 7 is the Event 1 state.
[6:0]
EVENT1_IDENTIFIER[6:0]
This bit represents the state of the event that is recorded in EVENT1_IDENTIFIER[6:0].
For key events (Event 1 to Event 96).
1 = key is pressed.
0 = key is released.
For GPI and logic events (Event 97 to Event 117).
1 = GPI/logic is active.
0 = GPI/logic is inactive.
Active and inactive states are programmable.
