WTIME
PTIME
The RGBC timing register controls the internal integration time of the RGBC clear and IR channel ADCs in
2.4-ms increments.
FIELD
ATIME
The proximity timing register controls the integration time of the proximity ADC in 2.4 ms increments. It is
recommended that this register be programmed to a value of 0xFF (1 cycle, 1023 bits).
FIELD
Wait time is set 2.4 ms increments unless the WLONG bit is asserted in which case the wait times are 12
WTIME is programmed as a 2’s complement number.
FIELD
Max Prox Count = ((256 − PTIME) × 1024)) − 1
