Abstract: A control circuit is provided. A memory is configured to store a program code. A central processing unit (CPU) executes a plurality of instructions according to the program code. When a specific instruction is executed by the CPU, the CPU generates a control signal. A power mode management circuit generates a selection signal according to the control signal. A processing circuit transforms first power data according to the selection signal. A first storage circuit stores the first power data. The processing circuit generates first set data and second set data according to first power data. A first specific device operates in a first power mode according to the first set data. A second specific device operates in a second power mode according to the second set data. The first storage circuit, the power mode management circuit and the processing circuit are in an always-on state.

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.
