Writing a one to this bit will enable the DMA module.
This bit is not enable-protected.
z Bit 0 – SWRST: Software Reset
0: There is no reset operation ongoing.
1: The reset operation is ongoing.
Writing a zero to this bit has no effect.
Writing a one to this bit when both the DMAC and the CRC module are disabled (DMAENABLE and CRCENABLE
is zero), resets all registers in the DMAC, except DBGCTRL, to their initial state If either the DMAC or CRC module
is enabled, the reset request will be ignored and the DMAC will return an access error.
