4.13 Control Port Operation
The control port is used to access control registers and on-chip memory locations, allowing the device to be configured for
desired operational modes and formats. Control port operation may be completely asynchronous with respect to the audio
sample rates. However, to avoid potential interference problems, control port pins must remain static if no operation is
required.
