Auto Request/Burst Mode/Normal Transfer Mode: When the DA bit is set to 1 in DMMDR, an
DMA transfer cycle is started a minimum of three cycles later. Once transfer is started, it
continues (as a burst) until the transfer end condition is satisfied.
Transfer requests for other channels are held pending until the end of transfer on the current
channel.
