WTIME

R/W

Sets the WaitTime between 2 measurements of the

modulator or sequencer. WTIME together with

MOD_TRIGGER_TIMING (in register 0xAE TRIGGER_

MODE) define the actual time between

measurements.

WaitTime = MOD_TRIGGER_TIMING x WTIME

Default: 0 = 0 x (0+1) no WaitTime

ALS Interrupt Low Threshold

The ALS interrupt threshold registers are 24-bit wide. ALS

interrupt level detection compares the threshold registers

with the data accumulated by the selected modulator. The

modulator can be selected via ALS_THRESHOLD_

CHANNEL. If AIEN is asserted and the accumulated data is

below AILT for the number of consecutive samples

specified in APERS, an interrupt is asserted on the

interrupt pin (internally AINT_AILT and AINT are asserted)
