Note: n = 0 to 3
Notes:
*1. This setting is valid only in DMABRG mode.
In external request 2-channel mode,
DREQ0 or DREQ1 can be accepted (only
for channel 0 or 1) regardless of this setting.
*2. The DMABRG settings are valid only in
channel 0. In DMABRG mode, when
selecting channel 0 transfer request source
in DMABRG, don’t change the channel 0
transfer request source after the DMABRG
DMA transfer starts. Normal operation is not
guaranteed if the transfer request source is
changed.
*3. Use this setting when the DMA transfer is
complete with the request in DMAC retained
(DMARCR.REXn = 1). See (3) Notes on
Ending Transfer in section 11.4.6, Ending
DMA Transfer.
