00 = 10 ms.
01 = 20 ms.
10 = 30 ms.
11 = 40 ms.
Configures the digital mux for Logic Block 2.
000 = off/disable.
001 = AND2.
010 = OR2.
011 = XOR2.
100 = FF2.
101 = IN_LA2.
110 = IN_LB2.
111 = IN_LC2.
Reserved.
0 = FF2 not set in Logic Block 2.
1 = set FF2 in Logic Block 2.
0 = FF2 not cleared in Logic Block 2.
1 = clear FF2 in Logic Block 2.
0 = FF1 not set in Logic Block 1.
1 = set FF1 in Logic Block 1.
0 = FF1 not cleared in Logic Block 1.
1 = clear FF1 in Logic Block 1.
Reserved.
0 = output of Logic Block 2 is debounced before entering the event/interrupt block.
0 = LY2 cannot generate interrupt.
1 = allow LY2 activity to generate events on the FIFO.
Configure the logic level of LY2 that generates an interrupt.
0 = LY2 is active low.
1 = LY2 is active high.
0 = output of Logic Block 1 is debounced before entering the event/interrupt block.
1 = output of Logic Block 1 is not debounced before entering the event/interrupt block. Use
with caution because glitches may generate interrupts prematurely.
0 = LY1 cannot generate interrupt.
1 = allow LY1 activity to generate events on the FIFO.
Configure the logic level of LY1 that generates an interrupt.
0 = LY1 is active low.
1 = LY1 is active high.
