5.3.2
There are 42 sources for internal interrupts from on-chip supporting modules.
5.3.3
Table 5.4 shows interrupt exception handling sources, vector addresses, and interrupt priorities.
For default priorities, the lower the vector number, the higher the priority.
Priorities among modules can be set by means of the IPR. The situation when two or more
modules are set to the same priority, and priorities within a module, are fixed as shown in
table 5.4.
For each on-chip supporting module there are flags that indicate the interrupt request status,
and enable bits that select enabling or disabling of these interrupts. If both of these are set to 1
for a particular interrupt source, an interrupt request is issued to the interrupt controller.
The interrupt priority level can be set by means of IPR.
The DMAC and DTC can be activated by a TPU, SCI, or other interrupt request. When the
DMAC or DTC is activated by an interrupt, the interrupt control mode and interrupt mask bits
are not affected.
