Read/write

0 = LC input not inverted before passing into the logic block.

1 = inverts input LC before passing it into the logic block.

4

LB_INV

R/W

0 = LB input not inverted before passing into the logic block.

1 = inverts input LB before passing it into the logic block.

3

LA_INV

R/W

0 = LA input not inverted before passing into the logic block.

1 = inverts input LA before passing it into the logic block.

2 to 0

LOGIC_SEL[2:0]

R/W

Configures the digital mux for the logic block. Refer to Figure 19.

000 = off/disable.

001 = AND.

010 = OR.

011 = XOR.

7 to 3

N/A

Reserved.

2

LY_DBNC_DIS

Read/write

0 = output of the logic block is debounced before entering the event/interrupt block.

1 = output of the logic block is not debounced before entering the event/interrupt

block. Use with caution because glitches may generate interrupts prematurely.

1

LOGIC_EVENT_EN

Read/write

0 = LY cannot generate interrupt.

1 = allow LY activity to generate events on the FIFO.

0

LOGIC_INT_LEVEL

Read/write

Configure the logic level of LY that generates an interrupt.

0 = LY is active low.

1 = LY is active high.
