The PDMC generates a clock in order to drive up to four PDM microphones. It embeds a SINC filter with programmable order (1 to 5) and an audio filter.
The audio filter can be disabled if specific filtering is required and performed by software.
The overall oversampling rate (OSR) can be configured to 64, 128 or 256 when the audio filter is enabled.
When the audio filter is disabled, the OSR of the SINC filter can be configured to 8, 16, 32, 64, 128 or 256.
