<p>PROBLEM TO BE SOLVED: To make it possible to place an alarm interruption function in operation at specific time on a specific day without interposing processing by software by using year, month, and day alarm information as operation condition information of an alarm interrupting function. SOLUTION: A real-time clock 18 is equipped with an hour, minute, and second counter register, a year, month, and day counter register, an hour, minute, and second alarm register, and a year, month, and day alarm register. Whether year, month, and day alarm information is used as operation condition information of the alarm interrupting function is set with environment setting information and the year, month, and day alarm register is so switched that it can be accessed only when year, month, and day alarm information is set as the operation condition information of the alarm interrupting function. Consequently, a user can selectively operate time management for initiating an alarm interruption at specific time on a specific day and time management for initiating an alarm interruption at arbitrary time of every day.</p> |
