Enable Register (0x00)
NOTE 1: A minimum interval of 2.4 ms must pass after PON is asserted before an RGBC can be initiated.

WTIME
The Enable register is used primarily to power the TCS3471 device on and off, and enable functions and
interrupts as shown in Table 3.
The RGBC timing register controls the internal integration time of the RGBC clear and IR channel ADCs in
2.4-ms increments. Max RGBC Count = (256 − ATIME)
FIELD
ATIME
Wait time is set 2.4 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.

Reserved. Write as 0.
RGBC interrupt enable. When asserted, permits RGBC interrupts to be generated.
Wait enable. This bit activates the wait feature. Writing a 1 activates the wait timer. Writing a 0 disables the
wait timer.
Reserved. Write as 0.
RGBC enable. This bit actives the two-channel ADC. Writing a 1 activates the RGBC. Writing a 0 disables
the RGBC.
Power ON. This bit activates the internal oscillator to permit the timers and ADC channels to operate.
Writing a 1 activates the oscillator. Writing a 0 disables the oscillator. During reads and writes over the I
interface, this bit is temporarily overridden and the oscillator is enabled, independent of the state of PON.
