Cautions 1. DBPC and DBPSW can be accessed only during the interval between the execution of an
Execution is returned from an exception trap by using the DBRET instruction. When the DBRET instruction is
executed, the CPU performs the following processing and transfers control to the address of the restored PC.
<1> Loads the saved PC and PSW from DBPC and DBPSW.
<2> Transfers control back to the address of the restored PC and PSW.
The processing for returning from an exception trap is shown below.
