0: The MDMA is in Fixed Priority Mode.
1: The MDMA is in Round-Robin Mode.
Writing a zero to this bit has no effect.
Writing a one to this bit disables the MDMA channel after the current transfer has completed.
To avoid hazards, CHxDIS bits can only be changed by writing a value to CR where the corresponding CHxEN bit is set.
This bit is automatically cleared by hardware when the corresponding channel has been disabled.
0: The channel is in Single Transfer Mode.
1: The channel is in Descriptor Mode.
To avoid hazards, CHxM bits can only be changed by writing a value to CR where the corresponding CHxEN bit is set.
Writing a zero to this bit this bit has no effect.
Writing a one to this bit enables the channel for DMA transfer.
This bit is automatically cleared if the transfer completes when the channel is in single transfer mode.
This bit is automatically cleared if the transfer completes when the channel is in descriptor mode, and the next descriptor read in
has a cleared Valid bit.
This bit is automatically cleared when the corresponding channel has been disabled by writing a one to CHxDIS.
