Peripheral transfer Width Select
00 = One word (32 bits) is transferred for every PDMA operation.
01 = One byte (8 bits) is transferred for every PDMA operation.
10 = One half-word (16 bits) is transferred for every PDMA operation.
11 = Reserved.
Note: This field is meaningful only when MODE_SEL is IP to Memory mode (APB-to-
Memory) or Memory to IP mode (Memory-to-APB).

Software Engine Reset
0 = Writing 0 to this bit has no effect.
1 = Writing 1 to this bit will reset the internal state machine, pointers and internal buffer.
PDMA Channel Enable
Setting this bit to 1 enables PDMA’s operation. If this bit is cleared, PDMA will ignore
all PDMA request and force Bus Master into IDLE state.
Note: SW_RST(PDMA_CSRx[1], x= 0~8) will clear this bit
The contents of control register will not be cleared. This bit will auto clear after few
clock cycles.
