Section 14 Direct Memory Access Controller (DMAC)
14.5
Pay attentions to the following notes when the DMAC is used.
14.5.1
While DMAC is in operation, modules should not be stopped by setting MSTPCR (transition to
the module standby state). When modules are stopped, transfer contents cannot be guaranteed.
14.5.2
When a DMA address error is occurred, after execute the following procedure, and then start a
transfer.
1. Dummy read for the below listed registers.
2. Issue the SYNCO instruction.
3. Set registers of all channels again.
14.5.3
During a burst mode transfer, following operation should not be executed until the transfer of
corresponding channel has completed.
• Frequency should not be changed.
• Transition to sleep mode should not be made.
