for SAR/DAR reload function, DMA transfer can be
performed until the transfer request is cancelled.

the DREQ signal is detected in external request mode,
the setting of this bit is ignored and DMA transfer stops
if the TE bit is set to 1.
Note that this function is enabled only when either the
RLDSAR bit or the RLDDAR bit is set to 1.
0: DMA transfer stops if the TE bit is set
1: DMA transfer does not stop even if the TE bit is set
