PROBLEM TO BE SOLVED: To provide an information processor capable of discriminating a temporary abnormality from a permanent abnormality of a micro controller.SOLUTION: A micro controller 1 has a function or the like for storing identification information for identifying from which AD channel an analog value is converted together with a digital value as an AD conversion result by an AD converter 10 in a specific address of an AD conversion result storage register 16. The micro controller 1 functions as abnormality detection means, and can detect an abnormality of the micro controller 1 by determining whether a corresponding AD conversion result is stored in an address of the AD conversion result storage register 16 corresponding to the identification information read from the AD conversion result storage register 16. The micro controller 1 functions as abnormality determination means, measures the number of times for detecting abnormalities of the micro controller 1, and discriminates a temporary abnormality from a permanent abnormality of the micro controller 1 in accordance with the number of times. |
