Abstract

PURPOSE: To make it possible to confirm and change the internal status of the program development evaluation chip to facilitate program debugging, by providing a monitor interrupting request terminal, a dedicated area, an interruption control circuit on the program development evaluation chip.
CONSTITUTION: Monitor interruption request terminal 13 is used as the request signal applied terminal of confirmation and change of the internal status of program development evaluation chip 12 during the execution of instructions of external memory 9. The transfer operation of program status PS14→shunting dedicated area SPS15 is executed by monitor interruption control circuit 16 according to the request signal to monitor interruption request terminal 13, and the transfer operation of SPS15→PS14 is executed according to the monitor interruption end signal. Consequently, it is possible to confirm and change easily the internal status of the program development chip of the one-chip microcomputer at an arbitary execution phase of the user program without changing the user execution program and the external control.
