Fast filter skip control (N + 1)
Full power to low power mode timeout control
Conversion reset control (self-clearing)
Full power mode proximity recalibration time control
Low power mode proximity recalibration time control
Description
0000 = no sequence of results is skipped
0001 = one sequence of results is skipped for every one
allowed into fast FIFO
0010 = two sequences of results are skipped for every
one allowed into fast FIFO
1011 = maximum value = 12 sequences of results are
skipped for every one allowed into fast FIFO
Calibration disable period in full power mode =
FP_PROXIMITY_CNT × 16 × time for one conversion
sequence in full power mode
Calibration disable period in low power mode =
LP_PROXIMITY_CNT × 4 × time for one conversion
sequence in low power mode
00 = 1.25 × (FP_PROXIMITY_CNT)
01 = 1.50 × (FP_PROXIMITY_CNT)
10 = 1.75 × (FP_PROXIMITY_CNT)
11 = 2.00 × (FP_PROXIMITY_CNT)
Forced calibration control
0 = normal operation
1 = forces all conversion stages to recalibrate
0 = normal operation
1 = resets the conversion sequence to STAGE0
Description
Proximity recalibration level; the value is multiplied by
16 to determine actual recalibration level
Proximity detection rate; the value is multiplied by 16 to
determine actual detection rate
Slow filter update level
