ADSP-SC584: setting the BCLK and LRCLK as master from SHARC DSP

Thank for the answer.

I have a question about setting the BCLK and LRCLK as master from SHARC DSP.

I want to work at 48KHZ with ADC ADAU1977 configured as slave.

As i understand i need to generate 3.072 Mhz BCLK from DSP (48KHZ * 64bit) so the LRCLK will run at 48KHZ.

1) How can i get the 3.072 Mhz freq from DSP if i use external OSC of 25 Mhz connected to CGU0 and CGU1 ?

2) I generated 3.125Mhz freq and defined LRCLK counter to 64 and i expected to see around 48.8khz on LRCLK

for some reason i see the 3.125Mhz with the probe on BCLK but there is no freq on LRCLK , what i'm doing wrong?
