6.2.9 PLL_AUDIO_XDIV_176 :
b7 b6 b5 b4 b3 b2 b1 b0
Address : 0xE4 (228)
Type : RW - DEC
Software Reset : 2
Description :
This register must contain a PEL value that enables
the system PLL to generate a frequency of 50 MHz
for the SYSCK. See table 4.
Default value at soft reset assume :
– external crystal provide a CRYCK running at
14.31818 MHz
Description :
This register must contain a XDIV value that enables
the audio PLL to generate a frequency of ofact*176
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
6.2.10 PLL_AUDIO_MDIV_176 :
b7 b6 b5 b4 b3 b2 b1 b0
Address : 0xE5 (229)
Type : RW - DEC
Software Reset : 8
Description :
This register must contain a MDIV value that enables
the audio PLL to generate a frequency of ofact*176
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
