Section 5 Interrupt Controller
(2) Determination of Priority
The DTC activation source is selected in accordance with the default priority order, and is not
affected by mask or priority levels. See section 8.3.3, DTC Vector Table, for the respective
priorities.
(3) Operation Order
If the same interrupt is selected as a DTC activation source and a CPU interrupt source, the DTC
data transfer is performed first, followed by CPU interrupt exception handling.
Table 5.11 summarizes interrupt source selection and interrupt source clearance control according
to the settings of the DTCE bit of DTCERA to DTCERG in the DTC, and the DISEL bit of MRB
in the DTC.

Legend:
O: The relevant interrupt is used. The interrupt source is not cleared.
X : The relevant bit cannot be used.
* : Don’t care
(4) Notes on Use
SCI and A/D converter interrupt sources are cleared when the DTC reads or writes to the
prescribed register.

: The relevant interrupt is used. Interrupt source clearing is performed.
(The CPU should clear the source flag in the interrupt handling routine.)
