Trigger point search device of microcontroller development system

摘要

The present invention discloses a trigger point searching apparatus of a microcontroller development system. A device capable of searching for a trigger point during execution of a program suspended in response to a stop signal includes at least one input means for inputting arbitrary data, Data comparing means for comparing the predetermined reference value with a predetermined reference value and outputting a comparison result signal as a comparison result, and data control means for outputting a stop signal in response to the comparison result signal. The wheel can immediately see the exact location and data value of the program with just one or N pins and MDS to solve the conventional inconvenience of using the MDS and oscilloscope to know the value or debugging the program from scratch. So that it is possible to perform debugging and error detection with ease.
