Section 6 Exception Handling
The interrupt exception handling is as follows:
1. The contents of PC, CCR, and EXR are saved in the stack.
2. The interrupt mask bit is updated and the T bit is cleared to 0.
3. An exception handling vector table address corresponding to the interrupt source is generated,
6.7
There are three instructions that cause exception handling: trap instruction, sleep instruction, and
illegal instruction.
6.7.1
Trap instruction exception handling starts when a TRAPA instruction is executed. Trap instruction
exception handling can be executed at all times in the program execution state. The trap
instruction exception handling is as follows:
1. The contents of PC, CCR, and EXR are saved in the stack.
2. The interrupt mask bit is updated and the T bit is cleared to 0.
3. An exception handling vector table address corresponding to the vector number specified in
A start address is read from the vector table corresponding to a vector number from 0 to 3, as
specified in the instruction code.
Table 6.8 shows the state of CCR and EXR after execution of trap instruction exception handling.

the start address of the exception service routine is loaded from the vector table to PC, and
program execution starts from that address.
the TRAPA instruction is generated, the start address of the exception service routine is loaded
from the vector table to PC, and program execution starts from that address.
