The relationship between the DMARQn signal and the interrupt source that serves as a DMA transfer trigger is as
follows (n = 0 to 3).
DMARQn
Interrupt source
Remark If an interrupt request is specified as the DMA transfer start factor, an interrupt request will be
generated if DMA transfer starts. To prevent an interrupt from being generated, mask the interrupt by
setting the interrupt request control register. DMA transfer starts even if an interrupt is masked.
