X
Enables the output of serial audio data (2 pins) plus serial bit clock and word select in a
format determined by the I
the outputs mentioned will be 3-stated, thereby improving the EMC performance
an MSB-aligned, MSB-first output format is selected, i.e. a level change at the word
select pin indicates the beginning of a new audio sample
the standard I
enables the output of a system (or master) clock signal at pin SYSCLK
the output will be off, thereby improving the EMC performance
