Figure 7.15 shows an example of the extended repeat area operation.
When an interrupt by an extended repeat area overflow is used in block transfer mode, the
following should be taken into consideration.
When a transfer is stopped by an interrupt by an extended repeat area overflow, the address
register must be set so that the block size is a power of 2 or the block size boundary is aligned with
the extended repeat area boundary. When an overflow on the extended repeat area occurs during a
transfer of one block, the interrupt by the overflow is suspended and the transfer overruns.
When the area represented by the lower three bits of DSAR (eight bytes)
is specified as the extended repeat area (SARA4 to SARA0 = B'00011)
