8.3.7
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.
The block size is 1 to 256. When the transfer of one block ends, the initial state of the block size
counter and the address register specified as the block area is restored. The other address register
is then incremented, decremented, or left fixed.
From 1 to 65,536 transfers can be specified. Once the specified number of transfers have ended, a
CPU interrupt is requested.
Table 8.8 lists the register information in block transfer mode and figure 8.8 shows the memory
map in block transfer mode.
