    Abstract: The display control device has a register for holding mode data for giving: a direction about which of a first display mode for performing display control of display data supplied together with a display timing signal from outside, and a second display mode for performing display control of display data written in RAM without accepting supply of a display timing signal from outside to select; and a direction about whether or not to select a scale-up mode for scaling up the display data, so that the mode data can be rewritten from the outside. The display mode is controlled based on the setting values on the register. The control register can be rewritten according to the type of data to be displayed, the system working situation, user settings, etc. Therefore, the low power consumption allowable in terms of system, and a required display performance can be obtained timely and readily.
