DMACSR
EQMASK
RW
[15:0]
0
Masks the input of the DMA data transfer
request input terminal DMASREQ[15:0].
When masked, only DMABREQ[15:0]
becomes valid.
0: DMASREQ input is masked
1: DMASREQ input is valid
Note that the setting of this register
changes the handshake method between
the DMAC and Peripherals and should be
used with care. When single data transfer
requests are disabled, only burst requests
can be accepted.

DMACExtControl_n
(n=0-3,step=0x20)
Indicates the control
information of each
channel’s transfer size,
burst size, transfer data
width, etc. during the
DMA data transfer. This
register must be set
before the corresponding
DMA channel is enabled.
When Scatter/Gather
transfer is being
performed, it will be
automatically updated to
the value of the
corresponding linked list.
