Transfer requests (activation sources) consist of A/D conversion end interrupt, SCI transmission
complete and reception complete interrupts, and TPU channel 0 to 2 compare match/input capture
A interrupts. For details, see section 7.3.4, DMA Control Register (DMACR). Figure 7.13 shows
an example of the setting procedure for block transfer mode.
