Abstract

An electronic apparatus with a touch panel including a host controller, an interface unit, and a touch panel control unit is provided. The host controller is used to control an electronic apparatus implemented with the host controller. The touch panel control unit is coupled to the host controller through the interface unit. The host controller transmits an updating information to the touch panel control unit with a format of the interface unit, in which the updating data is used to update the touch panel control unit. The touch panel control unit decodes the updating data to accordingly update.
