TRAP instruction
class A traps and to the resets.
Each class A traps has a dedicated trap number (and vector). They are prioritized in the second priority
level.
The resets have the highest priority level and the same trap number.
The PSW.ILVL CPU priority is forced to the highest level (15) when these exceptions are serviced.
