Abstract: A control circuit including an input-output pin, an image driver, a sensing circuit, a first path, a second path and a microcontroller circuit is provided. The input-output pin is configured to be coupled to the first pin of a display device and the second pin of a capacitive touch device. The image driver is configured to provide a driving signal. The sensing circuit determines whether the capacitive touch device is touched according to the voltage of the second pin. The microcontroller circuit turns on the first path and turns off the second path to transmit the driving signal to the display device via the input-output pin in a first operation period. The microcontroller circuit turns on the second path and turns off the first path to transmit the voltage of the second pin to the sensing circuit via the input-output pin in a second operation period.

Abstract: The present invention discloses a frequency signal enabling apparatus and the method thereof for filtering noises and glitch when entering an operating mode from a power-saving mode. When the pulse width of the input frequency signal is smaller than the threshold pulse width, it will be considered as a noise and be filtered out. When the high-level pulse width of the input frequency signal is greater than the threshold, a first short pulse will be generated. When the low-level pulse width of the input frequency signal is greater than the threshold, a second short pulse will be generated. The relative position of the first short pulse and the second short pulse will be used to reconstruct the frequency signal, and the reconstructed frequency signal may serve as the operating frequency of the microprocessor or other digital IC.
