Block Transfer Mode: Performs the transfer of one block for each one activation. Either the
transfer source or transfer destination is designated as the block area.
The block length is specified between 1 and 65536. 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 8.4 lists the register functions in block transfer mode. Figure 8.8
shows a memory map in block transfer mode.
