6.2 PLL_AUDIO_CONFIGURATION registers
description
6.2.1 PLL_AUDIO_PEL_192 :
b7 b6 b5 b4 b3 b2 b1 b0
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 :
– ofact == 256
– external crystal provide a CRYCK running at
14.31818 MHz
6.2.2 PLL_AUDIO_PEH_192 :
b7 b6 b5 b4 b3 b2 b1 b0
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 :
– ofact == 256
– external crystal provide a CRYCK running at
14.31818 MHz
6.2.3 PLL_AUDIO_NDIV_192 :
b7 b6 b5 b4 b3 b2 b1 b0
Address : 0xDE (222)
Type : RW - DEC
Software Reset : 0
