8.5.3
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 can be between 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 depending on its register
information.
From 1 to 65,536 transfers can be specified. Once the specified numbers of transfers have been
completed, a CPU interrupt is requested.
