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.
