System State Machine
The TCS3771 provides control of RGBC, proximity detection,
and power management functionality through an internal state
machine (Figure 19). 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 Prox, 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(s): 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).
