PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device capable of supplying clock signals with two kinds of frequencies through one clock signal line at the same time, capable of capturing data at an interval shorter than a half period, and capable of selecting a function execution means for executing asynchronous resetting through one reset signal line depending on a potential level of a reset signal. SOLUTION: The semiconductor integrated circuit device includes: a first function execution means including at least one latch means or over for capturing data when a potential level of a clock signal changes to a potential level from a potential level less than a threshold value of a particular potential level to a potential level being the threshold value or over; a second function execution means including at least one latch means or over for capturing data when a potential level of the clock signal changes to a potential level from a potential level less than a threshold value of a new particular potential level, smaller than the threshold value of the first function execution means, to a potential level being the new threshold value or over; a clock supply means for generating clock pulses for repeating at least two high potential levels or over and a potential level zero and supplying the clock to the first and second function execution means; and a voltage application means for applying at least two ore more high potential level values and a potential level zero to the first and second execution means and the clock supply means.
