6.2 PLL_AUDIO_CONFIGURATION registers
6.2.1
Address : 0xDC (220)
Type : RW - DEC
Software Reset : 58
Description :
This register must contain a PEL value that enables
the audio PLL to generate a frequency of ofact*192
kHz for the PCMCK.See table 1, 2 & 3.
ofact is the oversampling factor needed by the DAC
(ofac==246 or ofac==384).
Default value at soft reset assume :
6.2.2
Address : 0xDD (221)
Type : RW - DEC
Software Reset : 187
Description :
This register must contain a PEH value that enables
the audio PLL to generate a frequency of ofact*192
kHz for the PCMCK.See table 1, 2 & 3.
Default value at soft reset assume :
