Description
Destination Address Repeat Area
These bits specify the destination address
(EDDAR) repeat area. The repeat area function
updates the specified lower address bits, leaving
the remaining upper address bits always the same.
A repeat area size of 2 bytes to 8 Mbytes can be
specified. The setting interval is a power-of-two
number of bytes. When repeat area overflow
results from incrementing or decrementing an
address, the lower address is the start address of
the repeat area in the case of address
incrementing, or the last address of the repeat area
in the case of address decrementing. If the DARIE
bit is set to 1, an interrupt can be requested when
repeat area overflow occurs.
