Interrupt controller of DTC control has the following three main functions.
Interrupt Source Selection: For interruption source, select DTC activation request or CPU
interruption request by the DTCE bits in DTCERA to DTCERG, and DTCERI of the DTC. After
DTC data transfer, the DTCE bit is cleared to 0, and an interrupt request to the CPU can be made
by the setting of the DISEL bit in MRB of the DTC. When DTC performs data transfer for
prescribed number of times and transfer counter becomes 0, the DTCE bit should be cleared to 0
and an interrupt request to the CPU is made after DTC data transfer.
Priority Determination: DTC activation source is selected according to priority of default
setting. Mask level and priority level do not affect the selection. For details, see section 8.4,
Location of Register Information and DTC Vector Table.
