(2) Restoration
Execution is returned from a debug 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 address of the restored PC and PSW.
Caution DBPC and DBPSW can be accessed only during the interval between the execution of the
The processing for returning from a debug trap is shown below.
DBTRAP instruction and the DBRET instruction.
