8.4 - Exception and Error Traps List
Table 8 shows all of the possible exceptions or error conditions that can arise during run-time:
Table 8 : Trap Priorities
*
Reset Functions:
Class A Hardware Traps:
Class B Hardware Traps:
Reserved
Software Traps
15
- 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.

Group Level
Defines the internal order for simultaneous requests of the same priority.
3: Highest group priority
0: Lowest group priority
Interrupt Priority Level
Defines the priority level for the arbitration of requests.
Fh: Highest priority level
0h: Lowest priority level
Interrupt Enable Control Bit (individually enables/disables a specific source)
‘0’: Interrupt Request is disabled
‘1’: Interrupt Request is enabled
Interrupt Request Flag
‘0’: No request pending
‘1’: This source has raised an interrupt request
