Bit description

dis_ledoff

R/W

This register disables the utilization of the

aos_ledoff ambient light compensation offset

current register value to be used during the

LED off measurement phase for double and

triple sampling measurement mode. Instead,

the photodiode offset value of the subsample

is used during LED off phase for double and

triple measurement.

0: Register aoc_ledoff value used during

LED off phase for double and triple sampling

1: Register aoc_ledoff not used during LED

off phase for double and triple sampling

2:0

aoc_ovs

R/W

This register controls the AOC ADC

oversampling filter function whose input

signal is the decimation filter output of the

ADC modulator. The oversampling ratio is

calculated with the numerical register value

of aoc_ovs register to the power of two.

Please find the calculation formula below:

�� = 2

aoc_mod1_thh

255

R/W

This is the AOC high threshold register for

decreasing the ambient light offset current

for all subsamples for ADC modulator 1.
