TMD2725 − Register Description

The frequency of consecutive proximity channel results outside

of threshold limits are counted; this count value is compared

against the PPERS value. If the counter is equal to the PPERS

value an interrupt is asserted. Any time a proximity channel

result is inside the threshold values the counter is cleared.

The frequency of consecutive photopic channel results outside

of threshold limits are counted; this count value is compared

against the APERS value. If the counter is equal to the APERS

setting an interrupt is asserted. Any time a photopic channel

result is inside the threshold values the counter is cleared.
