TCS3400 − Register Description

RGBC Integration Time Register (ATIME 0x81)

The ATIME 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:

min [CYCLES * 1024, 65535]

Wait Time Register (WTIME 0x83)

The WTIME controls the amount of time in a low power mode.

It is set 2.78 ms increments unless the WLONG bit is asserted in

which case the wait times are 12x longer. WTIME is programmed

as a 2’s complement number. Upon power up, the wait time

Note(s):

1. The wait time register should be configured before AEN is asserted.
