Description
FP_PROXIMITY_CNT
4
0x002[7:4]
Calibration disable time in full power mode.
LP_PROXIMITY_CNT
4
0x002[11:8]
Calibration disable time in low power mode.
FP_PROXIMITY_RECAL
8
0x004[9:0]
Full power mode proximity recalibration time.
LP_PROXIMITY_RECAL
6
0x004[15:10]
Low power mode proximity recalibration time.
PROXIMITY_RECAL_LVL
8
0x003[7:0]
Proximity recalibration level. This value multiplied by 16 controls the
sensitivity of Comparator 2 (see Figure 34).
PROXIMITY_DETECTION_RATE
6
0x003[13:8]
Proximity detection rate. This value multiplied by 16 controls the
sensitivity of Comparator 1 (see Figure 34).

NOTES
1. SEQUENCE CONVERSION TIME
tCONV_LP = tCONV_FP + LP_CONV_DELAY.
2. PROXIMITY IS SET WHEN USER APPROACHES THE SENSOR, AT WHICH TIME THE INTERNAL CALIBRATION IS DISABLED.
3.
tCALDIS = (tCONV_LP × LP_PROXIMITY_CNT × 4).
