Internal Interrupts; Interrupt Exception Vector Table - Renesas Hitachi H8S/2194 Series Hardware Manual

6.3.2

Internal Interrupts

There are 38 sources for internal interrupts from on-chip supporting modules.
(1) 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 any one of these is set
to 1, an interrupt request is issued to the interrupt controller.
(2) The interrupt control level can be set by means of ICR.
6.3.3

Interrupt Exception Vector Table

Table 6.4 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 ICR. The situation when two or more modules
are set to the same priority, and priorities within a module, are fixed as shown in table 6.4.
