Example of demand transfer by software request (with DMAC ch0)
ー
(2) Set DMAC source address register
DMACSA0 ← 0x0100_8000
(1) Set DMA configuration register
DMACR ← 0x80 (byte writing)
Source address is set.
DMA transfer is enabled.
(3) Set DMAC destination address register
DMACDA0 ← 0xFFFE_1000
(4) Set DMA configuration B register
DMACB0 ← 0x2108_0000
Destination address is set.
Transfer mode, transfer data width, and completion
interrupt is set.
DMA channel transfer control, software trigger, and
number of block and transfer are set.
(5) Set DMA configuration A register
DMACA0 ← 0x9000_000A
Start DMA transfer
Remark: Setting order of step 1 ~ 5 is arbitrary; however, the last setting should be step 1 or 5.
Note:
•
DMA configuration register (DMACR) should be set by byte writes.
15.8.2 DMA start in all channels (in demand transfer mode)
All channels are able to start simultaneously by setting the DMACR register after setting all DMA
channel registers in demand transfer mode. In this case, the DMAC priority controller receives a
request from all channels at the same time, and then transfer starts by selecting the channel
according to the DMA channel priority, which is configurable using the PR bit of the DMACR.
