Description

PXDCAVG_AUTO_GTHR

Proximity Automatic Thresholds. When asserted, GTHR_IN

and GTHR_OUT are automatically written with a multiple of

the PBSLN every time PBSLN changes. The multiplication

factor is set in AUTO_GTHR_IN_MULT. PBSLN can only change

if PXDCAVG_AUTO_BASELINE is asserted and PBSLN_MEAS is

less than PBSLN.

PROX_AUTO_OFFSET_ADJUST

Proximity Auto Offset Adjust. If set, then during

proximity/gesture mode, whenever an ADC measurement is

zero, the appropriate offset register will be decreased. Will set

the OFFSET_ADJUSTED flag if it happens.

Reserved

5:4

Reserved.

PXDCAVG_AUTO_BASELINE

Proximity Automatic Baseline. When asserted,

PBSLN_MEAS is written to PBSLN whenever PBSLN_MEAS is

less than PBSLN. When this happens, the BASELINE_

ADJUSTED flag is raised. The default value is 1.

PXDCAVG_BASELINE_WINDOW

2:0

Prox Baseline Averaging Window. Sets the number of

proximity samples averaged to calculate PBSLN_MEAS, which

is updated at the end of each window. The default value is 16

samples.
