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).
