The source address extended repeat area is specified by bits SARA4 to SARA0 in EDACR, and
the destination address extended repeat area by bits DARA4 to DARA0 in EDACR. The size of
each extended repeat area can be specified independently.
When the address register value is the last address in the extended repeat area and extended repeat
area overflow occurs, EXDMA transfer can be temporarily halted and an extended repeat area
overflow interrupt request can be generated for the CPU. If the SARIE bit in EDACR is set to 1,
and the EDSAR extended repeat area overflows, the ESIF bit is set to 1 and the DTE bit cleared to
0 in EDMDR, and transfer is terminated. If the ESIE bit is set to 1 in EDMDR, an extended repeat
area overflow interrupt is requested to the CPU. If the DARIE bit in EDACR is set to 1, the above
applies to the destination address register. If the DTE bit in EDMDR is set to 1 during interrupt
generation, transfer is resumed.
Figure 11.15 illustrates the operation of the extended repeat area function.
