TCS3471 − Principles Of Operation

System State Machine

The TCS3471 provides control of RGBC and power management

functionality through an internal state machine (Figure 17).

After a power-on-reset, the device is in the sleep mode. As soon

as the PON bit is set, the device will move to the start state. It

will then continue through the Wait and RGBC states. If these

states are enabled, the device will execute each function. If the

PON bit is set to 0, the state machine will continue until all

conversions are completed and then go into a low power sleep

mode.

name in italics followed by the register number and bit number

to allow the user to easily identify the register and bit that

controls the function. For example, the power on (PON) is in
