TSL2771 − Principles O f Operation

System State Machine

The device provides control of ALS, proximity detection, 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 Prox, Wait,

and ALS 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
