Control Register (00h)
The CONTROL register contains two bits and is primarily used to power the TCS3404/14 device up and down
as shown in Table 4.

DESCRIPTION
Reserved. Write as 0.
Reserved. Write as 0.
ADC valid. This read-only field indicates that the ADC channel has completed an integration cycle.
Reserved. Write as 0.
ADC enable. This field enables the four ADC channels to begin integration. Writing a 1 activates the ADC
channels, and writing a 0 disables the ADCs.
Power on. Writing a 1 powers on the device, and writing a 0 turns it off.
t NOTES: 1. Both ADC_EN and POWER must be asserted before the ADC channels will operate correctly.
2. INTEG_MODE and TIME/COUNTER fields in the Timing Register (01h) should be written before ADC_EN is asserted.
G _{s 3. If a value of 03h is written, the value returned during a read cycle will be 03h. This feature can be used to verify that the device is}
communicating properly.
Technicaaml ^{scoAntent 4. During writes and reads, the POWER bit is overridden and the oscillator is enabled, independent of the state of POWER.}
