6.3.5
Tables 6.3 and 6.4 lists the codes for the interrupt event register (INTEVT and INTEVT2), and the
order of interrupt priority. Each interrupt source is assigned unique code. The start address of the
interrupt service routine is common to each interrupt source. This is why, for instance, the value of
INTEVT or INTEVT2 is used as offset at the start of the interrupt service routine and branched to
identify the interrupt source.
The order of priority of the on-chip peripheral module, IRQ, and PINT interrupts is set within the
priority levels 0 to 15 at will by using the interrupt priority level set to registers A to E (IPRA to
IPRE). The order of priority of the on-chip peripheral module, IRQ, and PINT interrupts is set to
zero by RESET.
When the order of priorities for multiple interrupt sources are set to the same level and such
interrupts are generated at the same time, they are processed according to the default order listed
in tables 6.3 and 6.4.
