(2) Restoration
Restoration from an exception trap is carried out by the DBRET instruction. By executing the DBRET instruction,
the CPU carries out the following processing and controls the address of the restored PC.
<1> Loads the restored PC and PSW from DBPC and DBPSW.
<2> Transfers control to the address indicated by the restored PC and PSW.
Caution DBPC and DBPSW can be accessed only during the interval between the execution of an illegal
