CHENn : PDMA Channel Enable Bit Set this bit to 1 to enable PDMAn operation. Channel cannot be active if it is not set as enabled. Note1: If software stops the corresponding PDMA transfer by setting PDMA_STOP register, this bit will be cleared automatically after finishing current transfer.

STOPn : PDMA Transfer Stop Control Register (Write Only) User can stop the PDMA transfer by STOPn bit field or by software reset (writing '0xFFFF_FFFF' to PDMA_STOP register).
