Section 8 DMA Controller (DMAC)
8.3.6
DMARCR controls automatic transfer of the DMAC setting information.
When using DMARCR to set registers, even though bits corresponding to the DTE bit in
DMAECRS or DMAECRF are 0, they will be set to 1 after all registers have been set.

Description
Setting Information Start Address
Set the start address where the setting information
of the relevant channel is located in these bits.
Setting Information Automatic Transfer Timing
When the setting condition is satisfied, the DMAC
automatically sets up the relevant channel based
on the setting information, according to the setting
of this bit.
1 can be written to this bit only when the DTE bit
of the relevant channel is 0.
Automatic transfer is performed when waiting for a
request by the activation source or in the transfer
disabled state on all channels.
0: Setting information is not transferred
1: Automatic setting is immediately performed
Setting Information Automatic Transfer Enable
The DMAC automatically sets up the relevant
channel based on the setting information.
0: Setting information is not transferred
1: Automatic setting is performed after transfer on
after this setting is completed
(Automatic setting is not performed when
transfer is interrupted by an error)
the relevant channel is completed
(Automatic setting is not performed when
transfer is interrupted by an error)
