7.6.14 ALS Down Delay

The ALS Down-Delay Register adds additional average time delays for ALS changes in the backlight current

during falling ALS input voltages. Code 00000 adds 3 extra average period delays on top of the 3 default delays

(6 total). Code 11111 adds 34 extra average period delays.
