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 control
2. The interrupt mask bit is updated and the T bit is cleared.
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 4.5 shows the status of CCR and EXR after execution of trap instruction exception handling.

Legend:
1: Set to 1
0: Cleared to 0
–: Retains value prior to execution.
