Abstract
PURPOSE: To improve a debug function considerably by preparing many start address registers and stop address registers to select plural trace positions of a program.
CONSTITUTION: Start address registers 21a, 21b, and 21c to store start addresses of trace and stop address registers 22a, 22b, 22c to store stop addresses of trace are provided. Pairs of registers 21a, 21b, and 21c and registers 22a, 22b, and 22c are selected one by one successively by a selection circuit consisting of AND circuit 23 and shift register 24. As a result, a debug function can be improved considerably.
