Section 8 Data Transfer Controller (DTC)
8.5.6
In block transfer mode, one operation transfers one block of data. Either the transfer source or the
transfer destination is designated as a block area by the DTS bit in MRB.
The block size is 1 to 256 bytes (1 to 256 words, or 1 to 256 longwords). When the transfer of one
block ends, the block size counter (CRAL) and address register (SAR when DTS = 1 or DAR
when DTS = 0) specified as the block area is restored to the initial state. The other address register
is then incremented, decremented, or left fixed. From 1 to 65,536 transfers can be specified. When
the specified number of transfers ends, an interrupt is requested to the CPU.
Table 8.8 lists the register function in block transfer mode. Figure 8.9 shows the memory map in
block transfer mode.
