I am working in an application based on example program named "Audio Codec TalkThrough - TDM (ASM)".
When I use the default values of CCLK and SCLK , the program runs perfectly, and I can hear the input signal on the output of ez-kit. But when I tried to increase the frequency of CCLK and SCLK the program runs but I can not hear anything on the output of ez-kit.
To change the values of CCLK and SCLK I used those codes :
p0.l = lo(VR_CTL);
p0.h = hi(VR_CTL);
r0.l = 0x00FB;
w[p0] = r0.l;
p0.l = lo(PLL_CTL);
p0.h = hi(PLL_CTL);
r1 = w[p0](z);
r2 = r1;
r0 = 0(z);
r0.l = 0x81ff;
r1 = r1 & r0;
r0.l = (0x16) << 9; // Changing the MSEL to 594MHz
r1 = r1 | r0; // Default MESL is 270MHz
w[p0] = r1; // Apply PLL_CTL changes.
Do you have any idea why i can not hear anything when i change the CCLK and SCLK frequency?
