Abstract
PURPOSE: To facilitate an easy debug for the program as well as the fault retrieval of the device by securing an automatic memorization for the career of the order address at the jump time and in synchronization with the order execution.
CONSTITUTION: FF14 is set in the writing mode, and line 20 is energized when the jump occurs at process oart 2. A comparison is given between the current executing address information supplied to line 27 from part 2 and jump address register 11 at comparator unit 4. And in case no coincidence is obtained, the current executing address on line 27 is set to register 11. The contents of address register 13 receives +1 by output 30 of gate 16 due to the signal on line 38, and furthermore the current executing address is memorized in the address of memory 10 designated by address register 13 and via memory control signal 35. After this, if the signal occurs to line 20, the same action as the above is given to memorize the new jump address in memory 10. And memory 10 is read out by setting FF15.
