slot here refers to the next instruction after a delayed unconditional branch instruction, or the next
instruction when a delayed conditional branch instruction is true.
4.2.4 Exception Codes
Table 4.3 lists the exception codes written to bits 11–0 of the EXPEVT register (for reset or
general exceptions) or the INTEVT register (for general interrupt requests) to identify each
specific exception event. An additional exception register, the TRAPA (TRA) register, is used to
hold the 8-bit immediate data in an unconditional trap (TRAPA instruction).
