Notes: 1. Priorities are indicated from high to low, 1 being highest and 4 being lowest.
4.2.3
Processor resets and interrupts are asynchronous events unrelated to the instruction stream. All
exception events are prioritized to establish an acceptance order whenever two or more exception
events occur simultaneously. When a power-on reset and a manual reset occur simultaneously, the
power-on reset has priority.
All general exception events occur in a relative order in the execution sequence of an instruction
(i.e., execution order), but are handled at priority level 2 in instruction-stream order (i.e., program
order), where an exception detected in a preceding instruction is accepted prior to an exception
detected in a subsequent instruction.
Three general exception events (general illegal instruction exception, unconditional trap exception,
and illegal slot instruction exception) are detected in the decode stage (ID stage) of different
instructions and are mutually exclusive events in the instruction pipeline. They have the same
execution priority. Figure 4.2 shows the order of general exception acceptance.
