Proximity Configuration

Proximity can be executed with its own sample rate

independent of and parallel to ALS/color integration. In this

case, PTIME is ignored and the proximity state is executed

before each ALS/color cycle. If PTIME is too short for the number

of pulses and pulse length configured for proximity, PROX_

TRIGGER_ERROR will be 1.
