Description
Repeat Enable
Used in combination with the DTIE bit in
DMABCR to select the mode (sequential, idle,
or repeat) in which transfer is to be performed.
When DTIE = 0 (no transfer end interrupt)
0: Transfer in sequential mode
1: Transfer in repeat mode
When DTIE = 1 (with transfer end interrupt)
0: Transfer in sequential mode
1: Transfer in idle mode
Data Transfer Direction
Used in combination with the SAE bit in
DMABCR to specify the data transfer direction
(source or destination). The function of this bit
is therefore different in dual address mode and
single address mode.
When SAE = 0
0: Transfer with MAR as source address and
1: Transfer with IOAR as source address and
When SAE = 1
0: Transfer with MAR as source address and
1: Transfer with DACK pin as read strobe and
IOAR as destination address
MAR as destination address
DACK pin as write strobe
MAR as destination address
