According to the PDM of the nRF52810 datasheet,the input of the filter is the two-channel PDM serial stream (with left channel on clock high, right channel on clock low), its output is 2 × 16-bit PCM samples at a sample rate 64 times lower than the PDM clock rate.One of the main features for PDM is 16kHz output sample rate.16kHz*64=1.024MHz.But the PDM clock rate we can select is 1.032 MHz(PDMCLKCTRL register).I have a question about this。
