Section 7 DMA Controller (DMAC)
7.5.7
In block transfer mode, data transfer is performed with channels A and B used in combination.
Block transfer mode can be specified by setting the FAE bit in DMABCRH and the BLKE bit in
DMACRA to 1. In block transfer mode, a data transfer of the specified block size is carried out in
response to a single transfer request, and this is executed for the number of times specified in
ETCRB. The transfer source is specified by MARA, and the transfer destination by MARB. Either
the transfer source or the transfer destination can be selected as a block area (an area composed of
a number of bytes or words). Table 7.10 summarizes register functions in block transfer mode.
Table 7.10 Register Functions in Block Transfer Mode
Register
MARA and MARB specify the start addresses of the transfer source and transfer destination,
respectively, as 24 bits. MAR can be incremented or decremented by 1 or 2 each time a byte or
word is transferred, or can be fixed. Incrementing, decrementing, or holding a fixed value can be
set separately for MARA and MARB. Whether a block is to be designated for MARA or for
MARB is specified by the BLKDIR bit in DMACRA.
To specify the number of transfers, if M is the size of one block (where M = 1 to 256) and N
transfers are to be performed (where N = 1 to 65,536), M is set in both ETCRAH and ETCRAL,
and N in ETCRB.
Figure 7.13 illustrates operation in block transfer mode when MARB is designated as a block area.
