-Priority of Exceptions

17.3 TLB Refill Vector Selection

Priority of Exceptions

The remainder of this chapter describes exceptions in the order of their priority shown in Table 17-3 (with certain of the exceptions, such as the TLB exceptions and Instruction/Data exceptions, grouped together for convenience). While more than one exception can occur for a single instruction, only the exception with the highest priority is reported. Some exceptions are not caused by the instruction executed at the time, and some exceptions may be deferred. See the individual description of each exception in this chapter for more detail.

Table 17-3 Exception Priority Order

Generally speaking, the exceptions described in the following sections are handled ("processed") by hardware; these exceptions are then serviced by software.
