Interrupt Vectors and Priority
Interrupt Assertion

Interrupts are globally disabled by any of the following actions:

The interrupt controller supports three levels of interrupt priority. Level 3 is the highest
priority, level 2 is the second highest priority, and level 1 is the lowest priority. If all the
interrupts are enabled with identical interrupt priority (all as level 2 interrupts, for
example), the interrupt priority is assigned from highest to lowest as specified in
on page 54. Level 3 interrupts are always assigned higher priority than level 2 interrupts
and level 2 interrupts are assigned higher priority than level 1 interrupts. Within each
interrupt priority level (level 1, level 2, or level 3), priority is assigned as specified in
Table 31
oscillator fail trap, Watchdog oscillator fail trap, and illegal instruction trap always have
highest (level 3) priority.
Interrupt sources assert their interrupt requests for only a single system clock period
(single pulse). When the interrupt request is acknowledged by the eZ8 CPU, the
corresponding bit in the interrupt request register is cleared. Writing 0 to the
corresponding bit in the interrupt request register clears the interrupt request.
The coding style listed below that clears the bits in the interrupt request registers is Not
recommended. All incoming interrupts received between execution of the first
command and the final
