Section 11 Direct Memory Access Controller (DMAC)
11.13 Usage Note
11.13.1 Note on Transition to Software Standby Mode or Deep Standby Mode
If the SLEEP instruction for transition to software standby mode or deep standby mode during
transfer by the DMAC, DMA transfer is not guaranteed because the DMAC stops without waiting
for transfer end. Therefore, when making transition to software standby mode or deep standby
mode, wait till DMA transfer ends or stop DMA transfer and then execute the SLEEP instruction.
Also when changing the PLL multiplication rate, stop DMA transfer in advance.
