Patent ID: 8212804

Claim:
An integrated circuit for controlling operations of a display module and a first circuit module, comprising: a shared pin; a display control module, for controlling operations of the display module externally coupled to the integrated circuit via the shared pin, wherein the display control module further generates a pin-sharing control signal according to an operation status of the display control module; a first control module, for controlling operations of the first circuit module externally coupled to the integrated circuit via the shared pin; and a pin-sharing management module, coupled to the display control module, the first control module and the shared pin, for granting one of the display control module and the first control module access to the shared pin according to the pin-sharing control signal, wherein the pin-sharing management module comprises: a data buffer unit; and an arbitration unit, for temporarily storing data which has not been transmitted completely between the first control module and the first circuit module into the data buffer unit, and granting the display control module the access right of the shared pin when receiving the pin-sharing control signal from the display control module.
