Note: The trap service routine must clear the respective trap flag, otherwise a new trap
The reset functions (hardware, software, watchdog) may be regarded as a type of trap.
Reset functions have the highest system priority (trap priority III).
Class A traps have the second highest priority (trap priority II), on the 3rd rank are class
B traps, so a class A trap can interrupt a class B trap. If more than one class A trap occur
at a time, they are prioritized internally, with the NMI trap on the highest and the stack
underflow trap on the lowest priority.
All class B traps have the same trap priority (trap priority I). When several class B traps
get active at a time, the corresponding flags in the TFR register are set and the trap
service routine is entered. Since all class B traps have the same vector, the priority of
service of simultaneously occurring class B traps is determined by software in the trap
service routine.

software causes the same effects as if it had been set by hardware.
