Bit[7:4]

This register sets the number of similar consecutive light sensor (LS) interrupt events that must occur

before the interrupt is asserted.

0000BIN

Every LS value out of threshold range (default) asserts an interrupt.

0001BIN

2 consecutive LS values out of threshold range assert an interrupt.

…

1111BIN

16 consecutive LS values out of threshold range assert an interrupt.

Bit[3:0]

Reserved.
