Electronic device and control method thereof

An electronic device, comprising:

• a host control circuit, configured to provide a first reset control signal;
• and
• a touch with display driver integration circuit, comprising:
• a display driving circuit, configured to perform reset operation according to the first reset control signal;
• a touch driving circuit;
• and
• a logic circuit, configured to generate a second reset control signal, according to the first reset control signal and an enable signal, to the touch driving circuit,
• wherein in a sleep mode of the electronic device, a rising edge of the first reset control signal triggers the display driving circuit to perform the reset operation,
• and in the sleep mode, the enable signal has a first logic level, wherein in response to the enable signal has the first logic level, the logic circuit generates the second reset control signal at the first logic level, and wherein the touch driving circuit does not reset according to the second reset control signal at the first logic level.

A control method, comprising:

• providing a first reset control signal by a host control circuit;
• providing an enable signal by a digital circuit;
• in an active mode, generating and outputting a second reset control signal to a touch driving circuit, by a logic circuit, according to logic level of the first reset control signal, and resetting the logic circuit according to the second reset control signal corresponding to the logic level of the first reset control signal;
• in a sleep mode, triggering a display driving circuit to perform reset operation according to a rising edge of the first reset control signal;
• and
• in the sleep mode, generating and outputting the second reset control signal to the touch driving circuit, by the logic circuit, according to logic level of the enable signal.
