Operation Order
If the same interrupt is selected as both the DTC activation source and CPU interrupt source, the
CPU interrupt exception handling is performed after the DTC data transfer. If the same interrupt is
selected as the DTC activation source or CPU interrupt source, respective operations are
performed independently.
Table 5.6 lists the selection of interrupt sources and interrupt source clear control by means of the
setting of the DTCE bit in DTCERA to DTCERH of the DTC, and the DISEL bit in MRB of the
DTC.

Usage Note
The interrupt sources of the SCI and A/D converter are cleared according to the setting shown in
table 5.6, when the DTC reads/writes the prescribed register.
To initiate multiple channels for the DTC with the same interrupt, the same priority should be
assigned.
