Section 8 DMA Controller (DMAC)
Transfer requests (activation sources) consist of A/D converter conversion end interrupts, external
requests, SCI transmit-data-empty and receive-data-full interrupts, and TPU channel 0 to 5
compare match/input capture A interrupts. External requests can only be specified for channel B.
