Register Settings Across Resets
The CS4207 will perform a complete Power On Reset (POR) initialization if the voltage is cycled from off to
on from the VD pin of the device. All registers will be initialized to the default state. For device behavior due
to other system reset conditions or power state transitions events, see the table below.
