Hi:
Can STM32F401's PCM be set as the following formats ?
PCM Slave , FS=8Khz ,BITS=16, Mono ( which means BCLK= 8khz * 16 = 128Khz)
After some tests , i find the PCM can only be used as stereo mode (BCLK = 8khz * 16 *2), is that true?
Thanks !!!

When both PCM master device and STM32F401 set with : 8Khz,16bits,stereo, it works fine.
When using mono mode, it seems that STM32F401 can recieve/send all bits ,but the bit position is mismatched.
Can someone could help me with this?

Hello,
Can you provide more details about your application? Are you trying to read data from a digital microphone with an audio sampling frequency= 8KHz?
