Abstract

PURPOSE: To make contents of a storage device fixed for the purpose of preventing unsightliness even if contents of the storage device are read and displayed until display data is inputted to the storage device after power supply to the device.
CONSTITUTION: When power is supplied, operations are executed according to the program counter, etc., as follows; in S1, the minimum address of color RAM 5 is designated by CPU 3, and data corresponding to a desired color, for example, blue data is inputted from CPU 3 to RAM 5 so that this data may be arranged in the bit part corresponding to back color information; and in S2, color write is performed to RAM 5. In S3, the address is increased by 1 advance to S4. In S4, "001" is written at the maximum address of RAM 5. In steps from S5 to S8, it is discriminated whether the control reaches the maximum address of display RAM 4 or not, and "000" is written at all addresses of display RAM 4, thus making storage contents fixed.
