Enable Register (0x00)
The Enable register is used primarily to power the TCS3771 device on and off, and enable functions and
interrupts as shown in Table 3.

DESCRIPTION
Reserved. Write as 0.
Proximity interrupt enable. When asserted, permits proximity interrupts to be generated.
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.
Proximity enable. This bit activates the proximity function. Writing a 1 enables proximity. Writing a 0
disables proximity.
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 I²C
interface, this bit is temporarily overridden and the oscillator is enabled, independent of the state of PON.
s _{NOTE 1: A minimum interval of 2.4 ms must pass after PON is asserted before either a proximity or an RGBC can be initiated. This required}
Technicaaml ^{scoAntent time is enforced by the hardware in cases where the firmware does not provide it.}
