8.4 - Exception and Error Traps List
Table 8 shows all of the possible exceptions or error conditions that can arise during run-time:
*
- All the class B traps have the same trap number (and vector) and the same lower priority compare to the 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.
