4.6
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 values in the program counter (PC), condition code register (CCR), and extended register
2. The interrupt mask bit is updated and the T bit is cleared to 0.
3. A vector address corresponding to the interrupt source is generated, the start address is loaded
The TRAPA instruction fetches a start address from a vector table entry corresponding to a vector
number from 0 to 3, as specified in the instruction code.
Table 4.4 shows the status of CCR and EXR after execution of trap instruction exception handling.

from the vector table to the PC, and program execution starts from that address.
