Section 5 Interrupt Controller
Operation Order: When the same interrupts are selected as DTC activation source and CPU
interruption source, DTC data is transferred, and then CPU interrupt exception processing is made.
Table 5.9 shows interrupt source selection and interrupt source clear control by the setting of the
DTCE bit in DTCERA to DTCERG, and DTCERI of the DTC and the setting of the DISEL bit in
MRB of the DTC.

Usage Note: Interrupt sources of the SCI and A/D converter are cleared when the DTC reads or
writes prescribed register, and they do not depend on the DTCE or DISEL bit.

5.6.1
When an interrupt enable bit is cleared to 0 to disable interrupt requests, the disabling becomes
effective after execution of the instruction.
When an interrupt enable bit is cleared to 0 by an instruction such as BCLR or MOV, and if an
interrupt is generated during execution of the instruction, the interrupt concerned will still be
enabled on completion of the instruction, and so interrupt exception handling for that interrupt will
be executed on completion of the instruction. However, if there is an interrupt request of higher
priority than that interrupt, interrupt exception handling will be executed for the higher-priority
interrupt, and the lower-priority interrupt will be ignored.
