System State Machine
The LUMENOLOGY r Company
The TCS3471 provides control of RGBC and power management functionality through an internal state
machine (Figure 6). 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.
NOTE: In this document, the nomenclature uses the bit field 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 register 0, bit 0. This is represented as PON (r0:b0).
