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.
•
0: Transfer in sequential mode
1: Transfer in repeat mode
•
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.
•
0: Transfer with MAR as source address and IOAR
1: Transfer with IOAR as source address and MAR
•
0: Transfer with MAR as source address and DACK
1: Transfer with DACK pin as read strobe and MAR
as destination address
as destination address
pin as write strobe
as destination address
When DTIE = 0 (no transfer end interrupt)
When DTIE = 1 (with transfer end interrupt)
When SAE = 0
When SAE = 1
