RGBC Integration Time Register
The RGBC timing register controls the internal integration time
of the RGBC channel ADCs. Upon power up, the RGBC time
register is set to 0xFF.
The maximum (or saturation) count value can be calculated
based upon the integration time cycles as follows:

Wait Time Register
Wait time is set in 2.38 ms increments unless the WLONG bit is
asserted in which case the wait times are 12× longer. WTIME is
programmed as a 2’s complement number.
