Description
Destination Address Extended Repeat Area
Specify the extended repeat area on the destination
address (DDAR). With the extended repeat area, the
specified lower address bits are updated and the
remaining upper address bits are fixed. The extended
repeat area size is specified from four bytes to 128
Mbytes in units of byte and a power of 2.
When the lower address is overflowed from the
extended repeat area by address update, the address
becomes the start address and the end address of the
area for address addition and subtraction, respectively.
When an overflow in the extended repeat area occurs
with the DARIE bit set to 1, an interrupt can be
requested. Table 7.2 shows the settings and areas of
the extended repeat area.
