Note Do not set the DFn bit to “1” by software.
Cautions 1. For the IFCn5 to IFCn0 bits, see Table 19-1 DMA Transfer Start Factors.
If the interrupt specified as the DMA transfer start factor occurs and it is necessary to clear the DMA
transfer request while DMA transfer is disabled (including when it is forcibly terminated by software), stop
the operation of the source causing the interrupt, and then write 0 to the DFn bit (for example, disable
reception in the case of serial reception). If it is clear that the interrupt will not occur until DMA transfer is
resumed next, it is not necessary to stop the operation of the source causing the interrupt.
2. Be sure to set bit 6 to “0”. If it is set to “1”, the operation is not guaranteed.
