To start processing the bitstream coming from the PDM interface, follow the steps below:

1. Clear all bits in the Control Register (PDMIC_CR) or compute a soft reset using the SWRST bit of PDMIC_CR.
2. Configure the PRESCAL field in PDMIC_MR according to the microphone specifications.
3. Enable the PDM mode and start the conversions using the ENPDM bit in PDMIC_CR.
