(2) Determination of priority
The DTC startup source is selected according to the default priority. This is not influenced by the
mask level or the priority level. See section 9.4, Location of Register Information and DTC Vector
Table, for details on these priorities.
The startup sources are directly input to each channel in the DMAC*.
Note: * Supported only by the H8S/2239 Group.
(3) Operating Sequence
When the same interrupt is selected as both the DTC startup source and a CPU interrupt source,
the DTC data transfer is performed and then the CPU interrupt exception handling is performed.
When the same interrupt is selected as both the DMAC* startup source and either the DTC startup
source or a CPU interrupt source, the operations are performed independently. They are performed
according to the operating states and the bus priorities.
Table 5.9 shows the interrupt source selection and the interrupt source clear control according to
the settings of the DMAC* DMABCR DTA bit, the DTC DTCERA to DTCERF DTCE bits, and
the DTC MRB DISEL bit.
Note: * Supported only by the H8S/2239 Group.
