MAIN PROGRAM

Figure 19-3 Timing Diagram after Reset

The Address Fail Reset is the function to reset the system by

checking code access of abnormal and unwished address caused

by erroneous program code itself or external noise, which could

not be returned to normal operation and would become malfunc-

tion state. If the CPU tries to fetch the instruction from ineffective

code area or RAM area, the address fail reset is occurred. Please

refer to Figure 11-2 for setting address fail option.
