The control port is used to load all the internal register settings (see section 5). The operation of the control

port may be completely asynchronous with the audio sample rate. However, to avoid potential interference

problems, the control port pins should remain static if no operation is required.

MAP Auto Increment

The device has MAP (memory address pointer) auto increment capability enabled by the INCR bit

or reads, and SPI writes. If INCR is set to 1, MAP will auto increment after each byte is written,

allowing block reads or writes of successive registers.
