A DEVICE DETECTING TRIGGER POINT IN MICRO-CONTROLLER DEVELOPMENT SYSTEM

摘要

The present invention discloses a trigger point search apparatus of a microcontroller development system. During execution of a program in which execution is stopped in response to a stop signal, the apparatus capable of searching for a trigger point includes at least one input means for inputting arbitrary data, and inputs arbitrary data from the input means in advance. It is preferable that the data comparison means comprises a data comparison means for comparing with a predetermined reference value and outputting a comparison result signal as a comparison result, and a data control means for outputting a stop signal in response to the comparison result signal. When you use an MDS and an oscilloscope to know the changing value, or to eliminate the conventional inconvenience of having to debug the program from scratch, you can immediately see the exact location and data values of the program with just one or N pins and the MDS. Therefore, there is an effect that can perform easy debugging and error detection.
