Micronas

D0:7f1

Main I/O Control (reset = 124hex)

All

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) is expected at the serial input

interface SDIB. In the 8-bit-parallel input mode (default) the PIO pins PI[19:12]

are used.
