5.5.1
Exception processing can be triggered by trap instruction, illegal slot instructions, and general
illegal instructions, as shown in table 5.9.
Table 5.9
5.5.2
When a TRAPA instruction is executed, trap instruction exception processing starts. The CPU
operates as follows:
1. The status register (SR) is saved to the stack.
2. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
3. The CPU reads the start address of the exception service routine from the exception processing

to that address and starts excuting the program. This jump is not a delayed branch.
