<p>PROBLEM TO BE SOLVED: To provide a microcomputer capable of surely initializing hardware only when needed for a system and preventing runaway due to noise in the system control of electronic equipment. SOLUTION: For the reset signal of the electronic equipment, by setting an input period standardized matched with the specifications to a comparator 104, in the case that the input period of signals inputted to a reset terminal 101 is the standard cycle of the reset signal or less, the input signals are removed as noise. Also in the case that a vector address can not be separated in the hardware, a RAM holding the measured result of the input period is discriminated by software and the system control of the electronic equipment is branched to a program matched with user specifications.</p> |
