Bit Description

7DCAVG_AUTO_BSLN

R/W

DC Averaging Automatic Baseline. Load the DC

average calculated during offset calibration into the

PBSLN registers at the end of calibration. Note that if

the offset is adjusted (by zero detection) during the

DC averaging, the average may be incorrect.

DCAVG_AUTO_OFFSET_

ADJUST

0R/W

DC Averaging Auto Offset Adjust. If set, then

during DC averaging, whenever an ADC

measurement is zero, the appropriate offset register

will be decreased and the OFFSET_ADJUSTED flag is

set. Note also that DC averaging is not automatically

restarted when this happens, so the calculated

baseline might be wrong. Software could restart

averaging in this case.

5:4

Reserved

BINSRCH_SKIP

R/W

Binary Search Skip. When asserted the calibration

routine will skip the binary search step. It is useful if

zeroes are detected during the DC averaging process

to manually reset the baseline and reduce the

likelihood of zero counts.

2:0

DCAVG_ITERATIONS

R/W

DC Averaging Iterations. Sets the number of

proximity results during calibration that are

averaged after the binary search is complete. During

this period, whenever a result is zero, the appropriate

offset register is automatically decremented.
