Main I/O Control
(reset = 8025

)
IOControlMain is used for selecting/deselecting the appropriate data input
interface and for setting up the serial data output interface. In serial input
mode the coded audio data (Layer 2, Layer 3, AAC) is expected at the serial
input interface SDIB (default). In the 8-bit-parallel input mode the PIO pins
PI[19:12] are used.

incoming clock signal is inverted (data latched at
falling clock edge)

no forced evaluation of control memory cells
changes in control memory will become effective
Bit[0] is reset after the DSP has recognized the changes. The controller
should set this bit after the other D0 control memory cells have been initialized
with the desired values.
