Note: This target is relative to 8-bit ADC values. In

the circuit, a 10-bit target is used (x4) of which the

lowest 2 bits are always ignored when checking for

zero during binary search and zero detection.

In hardware, this defines a mask of which bits to

ignore when comparing to zero. e.g. binsrch_

target=4 (target=15) means that values from the

ADC are AND'ed with 0xffc0 before comparing to

zero. Only values 16 or larger are taken as positive

ADC values.

Reserved

Reserved. Set to 1.

prox_auto_offset_

adjust

0SC

This bit enables an automatic adjustment of the

offset used in proximity measurements. If this bit is

set, when a measurement returns zero, the value of

0xC0 will be decremented and offset_adjusted flag

will be set, bit 2 in 0xDC.
