ZERO_DETECTED

Zero Detected. Indicates that zeroes are being detected in

proximity or gesture often enough to exceed the ZERO_WEIGHT

conditions. Recalibration is recommended. Bit generates interrupt if

CIEN is asserted. To prevent interrupt, set ZERO_WEIGHT to zero.

Clear this bit by writing ‘1’ to it.

BASELINE_ADJUSTED

Proximity/Gesture Baseline Adjusted. Indicates that the

proximity baseline, PBSLN, has changed. This may occur in two

ways:

During DC averaging at calibration, if DCAVG_AUTO_BASELINE is

asserted (independent of actual value).

During regular proximity/gesture operation if

DCAVG_AUTO_BASELINE is set and a new PBSLN_MEAS value is

collected that is lower than previous PBSLN).

Bit generates interrupt if CIEN is asserted. To prevent interrupt, set

DCAVG_AUTO_BASELINE and PXDCAVG_AUTO_BASELINE to zero.

Clear bit by writing '1' to it or by writing '1' to INTCLEAR_CINT.

OFFSET_ADJUSTED

Proximity/Gesture Offset Adjusted. Indicates that one or more

proximity/gesture offset register values were automatically

adjusted. Bit generates interrupt if CIEN is asserted. To prevent

interrupt, set DCAVG_AUTO_OFFSET_ADJUST and

PROX_AUTO_OFFSET_ADJUST to zero. Clear bit by writing '1' to it.

CALIB_FINISHED

Calibration Finished. Indicates that calibration is complete. Bit

generates interrupt if CIEN is asserted. Clear bit by writing '1' to it.
