d. <E>
• DMAC configuration flow
Note: Please set Burst size equivalent to the FIFO size of Peripheral.
Ex: using DMAC ch1, transfer from Memory to built-in FIFO of I
Total transfer data size: 32 words
Transfer count unit: Swidth = Word
Total transfer count: 32 counts
To temporarily stop DMA transfer, use the <Halt> bit to disable DMA requests, poll the
<Active> bit until it becomes 0, and then clear the <E> bit to disable the channel.
• DMACCxConfiguration (DMAC Channel x Configuration Register)(x = 0 to 7)
This bit is used to enable or disable the channel. If the channel is disabled during a transfer,
the data in the channel’s FIFO will be lost. To re-start, the channel must be reset.
<SrcPeripheral>
This is a DMA request peripheral number in binary.
This setting will be ignored if memory is specified as the transfer destination.
This is a DMA request peripheral number in binary.
This setting will be ignored if memory is specified as the transfer source.
The structure and description of these registers are same as DMACC0Configuration.
Please refer to the description of DMACC0Configuration.
The name and addresse of these registers, please refer to Table 3.8.3.
