Configuration Register
Proximity Pulse Count Register (0x0E)
The proximity pulse count register sets the number of proximity
pulses that the LDR pin will generate during the Prox Accum
state.

ALS gain level. When asserted, the 1x and 8x ALS gain (AGAIN) modes are scaled by
0.16. Otherwise, AGAIN is scaled by 1. Do not use with AGAIN greater than 8x.
WLONG
1
Wait Long. When asserted, the wait cycles are increased by a factor 12x from that
programmed in the WTIME register.
PDL
0
Proximity drive level. When asserted, the proximity LDR drive current is reduced by 9.
