Abstract:
A clock circuit is suitable for use in a timing circuit which provides time information according to a reference clock. The clock circuit includes a clock detector to detect whether or not an interruption of the reference clock occurs. When the interruption of the reference clock occurs, a clock interruption signal is issued as a reference whether or not to reset the timing circuit.
