ABSTRACT:
A start-up circuit receives a start-up signal instructing start-up of an equipment mounted with the circuit, and executes a predetermined sequence when start-up is instructed by the start-up signal. An oscillator generates a clock signal. A sequence circuit receives the start-up signal and a clock signal output from the oscillator, measures time by counting the clock signal when the start-up signal transits to a predetermined level, and executes a predetermined event at a predetermined timing. The oscillator operates for a period where the start-up signal is at the predetermined level if the start-up signal is at the predetermined level during the period the power key of the equipment mounted with the circuit is being pushed.
