Nothing is assigned.
These bits can neither be set nor reset. When read, the value of these bits is “0”.
Software DMA request bit
If software trigger is selected, a
DMA request is generated by
setting this bit to “1” (When read,
the value of this bit is always “0”)

Nothing is assigned.
These bits can neither be set nor reset. When read, the value of these bits is “0”.
Note 1: DMA request can be cleared by resetting the bit.
Note 2: This bit can only be set to “0”.
Note 3: Source address direction select bit and destination address direction select bit
cannot be set to “1” simultaneously.
