Description
Fast filter skip control (N+1)
0000 = no sequence of results are 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
Full power mode proximity period
Low power mode proximity period
Full power to low power mode time out control
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
Conversion reset control (self-clearing)
0 = normal operation
1 = resets the conversion sequence back to STAGE0
Description
Proximity recalibration level
Proximity detection rate
Slow filter update level
Description
Full power mode proximity recalibration time control
Low power mode proximity recalibration time control
