(2)
The DTC activation source is selected according to the default priority, and the selection is not
affected by its mask level or priority level. For respective priority levels, see table 8.1, Interrupt
Sources, DTC Vector Addresses, and Corresponding DTCEs.
(3)
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 or DMAC activation source or CPU interrupt source, respective operations
are performed independently.
Table 6.6 lists the selection of interrupt sources and interrupt source clear control by setting the
DTA bit in DMDR of the DMAC, the DTCE bit in DTCERA to DTCERG of the DTC, and the
DISEL bit in MRB of the DTC.
Table 6.6
[Legend]
√: The corresponding interrupt is used. The interrupt source is cleared.
O: The corresponding interrupt is used. The interrupt source is not cleared.
X: The corresponding interrupt is not available.
*: Don't care.
(4)
The interrupt sources of the SCI, and A/D converter are cleared according to the setting shown in
table 6.6, when the DTC or DMAC reads/writes the prescribed register.
To initiate multiple channels for the DTC with the same interrupt, the same priority (DTCP =
DMAP) should be assigned.
