20.6.2 Debug trap
instruction.
The debug trap is an exception that can be acknowledged anytime and is generated by execution of the DBTRAP
When the debug trap is generated, the CPU performs the following processing.
(1) Operation
<1> Saves the restored PC to DBPC.
<2> Saves the current PSW to DBPSW.
<3> Sets the PSW.NP, PSW.EP and PSW.ID bits (1).
<4> Sets the handler address (00000060H) corresponding to the debug trap to the PC and transfers control.
The processing of the debug trap is shown below.
