Table 5.8 shows a setting example of the priority control function over the DTC and DMAC and

the transfer request control state. A priority level can be independently set to each DMAC channel,

but the table only shows one channel for example. Transfers through the DMAC channels can be

separately controlled by assigning different priority levels for channels.
