YSS912C Datasheet, PDF (8/14 Pages) List of Unclassifed Manufacturers – DOLBY DIGITAL (AC-3) / PRO LOGIC / DTS DECODER + SUB DSP

YSS912C
CONTROL REGISTER
The decoding system is controlled by reading and writing the control registers through microprocessor interface
(/CS, SCK, SI and SO).
Note : All bits are set to “0” by initial clear (/IC=0) except bit 4 of PLL/DSN register (0x00).
