A disclosed timer circuit for clocking a predetermined time includes an oscillator and a frequency dividing unit for dividing a frequency of an oscillating signal output from the oscillator. A comparing unit determines whether a short-time mode instruction is received by comparing a voltage received at an external terminal with a predetermined voltage. A switch causes the oscillating signal to bypass a part of the frequency dividing unit in response receiving the short-time mode instruction.
