I am currently using the PCM3794RHBT codec with the 40 MHz system clock provided by a DSP chip. I want the audio to be at 48 kHz sampling rate. What do I need to set the MSR setting in the “BCK configuration, sampling rate control, zero-cross” register (0x56) and the NPR setting in the “System reset, sampling rate control” register (0x58). I can change the System clock to 20 MHz, 13.33 MHz and 10 MHz.
