PDM Operation
1.
Setup M0_CK, M3_CK to decide the MCK.(Please refer to Section 5.1 for detailed instruction for setup)
2.
Set PDMEN to enable the PDM Module.
3.
Setup PMCS[2:0] to decide the PDM CLK frequency.
4.
Setup PMD1[15:0] to decide the PDM output signal.
5.
Set PT2EN[2] to assign the PT2[2] to be an output port.
6.
Set PM1EN to assign the PT2[2] to be PDM Module output.
