Undefined Instruction Interrupt (INTUNDEF)
Address Trap Interrupt (INTATRAP)
Taking code which is not defined as authorized instruction for instruction causes INTUNDEF. INTUNDEF is
Fetching instruction from unauthorized area for instructions (Address trapped area) causes reset output or address
Note:The undefined instruction interrupt (INTUNDEF) forces CPU to jump into vector address, as software interrupt
Note:The operating mode under address trapped, whether to be reset output or interrupt processing, is selected on
and an address error is detected. The address error detection range can be further expanded by writing FFH to
unused areas of the program memory. Address trap reset is generated in case that an instruction is fetched from
RAM, DBR or SFR areas.

Debugging
Debugging efficiency can be increased by placing the SWI instruction at the software break point setting
