Destination Address Update Mode
These bits specify incrementing/decrementing of the
transfer destination address (DMDAR). When an
external device with DACK is designated as the transfer
destination in single address mode, the specification by
these bits is ignored.
0X: Destination address (DMDAR) is fixed
10: Destination address is incremented (+1 in byte
11: Destination address is decremented (–1 in byte
Destination Address Repeat Interrupt Enable
Description
When this bit is set to 1, in the event of destination
address repeat area overflow the IRF bit is set to 1 and
the DA bit cleared to 0 in DMMDR, and transfer is
terminated. If the DIE bit in DMMDR is 1 when the IRF
bit in DMMDR is set to 1, an interrupt request is sent to
the CPU.
When used together with block transfer mode, a
destination address repeat interrupt is requested at the
end of a block-size transfer.
If the DA bit is set to 1 in DMMDR for the channel on
which transfer is terminated by a destination address
repeat interrupt, transfer can be resumed from the state
in which it ended.
If a destination address repeat area has not been
designated, this bit is ignored.
0: Destination address repeat interrupt is not requested
1: When destination address repeat area overflow
occurs, the IRF bit in DMMDR is set to 1 and an
interrupt is requested
