Figure 7.12 shows a sample setup procedure for block transfer mode.
Note: Carry out settings 1 to 10 with the DEND interrupt masked in the CPU.

Set source address
If an NMI interrupt occurs during the setup procedure, it may clear the DTME bit to 0, in
which case the transfer will not start.

Read DTCRB with DTME cleared to 0.
Set the DTME bit to 1 in DTCRB.
Read DTCRA with DTE cleared to 0.
Set the DTE bit to 1 in DTCRA to enable
the transfer.
Clear the DTME bit to 0.
Set the DAID and DAIDE bits to select whether
MARB is incremented, decremented, or held fixed.
Set or clear the TMS bit to make the block area
the source or destination.
Select the DMAC activation source with bits
DTS2B to DTS0B.
Clear the DTE to 0.
Select byte size or word size with the DTSZ bit.
Set the SAID and SAIDE bits to select whether
MARA is incremented, decremented, or held fixed.
Set or clear the DTIE bit to enable or disable the
CPU interrupt at the end of the transfer.
Set bits DTS2A to DTS0A all to 1 to select
block transfer mode.
