8.3.7
In block transfer mode, one operation transfers one block of data.
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 8-7 lists the register information in block transfer mode and figure 8-8 shows memory mapping in block transfer
mode.
