AIC34_PLLB_CLK_GEN



Hi:

I am trying to generate a clock from pll of codec b on the AIC34. The input to pll-b is a 19.2 MHz clock on gpio2-b. The pll is programmed to generate an output clock of 12.288 MHz on gpio1-b (fs(ref)=48 KHz). Howeever, I am not seeing any signal on gpio1-b. It remains high. I am using the script below to accomplish this. Could you please let me know what I am missing?

Thanks a lot!

Cheers,

Mushtaq
