Interrupt Vector Table - Hitachi H8/3035 Series Hardware Manual

5.3.3 Interrupt Vector Table

Table 5-3 lists the interrupt sources, their vector addresses, and their default priority order. In the
default priority order, smaller vector numbers have higher priority. The priority of interrupts
other than NMI can be changed in IPRA and IPRB. The priority order after a reset is the default
order shown in table 5-3.
