5.7.2
When a TRAPA instruction is executed, trap instruction exception handling starts. The CPU
operates as follows:
1. The exception service routine start address which corresponds to the vector number specified
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the start address of the
4. After jumping to the address fetched from the exception handling vector table, program
5.7.3
An instruction placed immediately after a delayed branch instruction is said to be placed in a delay
slot. When the instruction placed in the delay slot is undefined code, an instruction that rewrites
the PC, a 32-bit instruction, an RESBANK instruction, a DIVS instruction, or a DIVU instruction,
slot illegal exception handling starts when such kind of instruction is decoded. The CPU operates
as follows:
1. The exception service routine start address is fetched from the exception handling vector table.
2. The status register (SR) is saved to the stack.
3. The program counter (PC) is saved to the stack. The PC value saved is the jump address of the
4. After jumping to the address fetched from the exception handling vector table, program
5.7.4
When undefined code placed anywhere other than immediately after a delayed branch instruction
(delay slot) is decoded, general illegal instruction exception handling starts. The CPU handles
general illegal instructions in the same way as slot illegal instructions. Unlike processing of slot
illegal instructions, however, the program counter value stored is the start address of the undefined
code.
