TCS3472 − Principles of Operation

System States

An internal state machine provides system control of the RGBC

and power management features of the device. At power up,

an internal power-on-reset initializes the device and puts it in

a low-power Sleep state.

When a start condition is detected on the I²C bus, the device

transitions to the Idle state where it checks the Enable Register

(0x00) PON bit. If PON is disabled, the device will return to the

Sleep state to save power. Otherwise, the device will remain in

the Idle state until the RGBC function is enabled (AEN). Once

enabled, the device will execute the Wait and RGBC states in

sequence as indicated in Figure 16. Upon completion and

return to Idle, the device will automatically begin a new

Wait-RGBC cycle as long as PON and AEN remain enabled.
