One-chip semiconductor integrated circuit device capable of outputting analog color signal or digital color signal |
摘要 |
A semiconductor device (CPLT) of the invention comprises a first terminal (R) to which analog data is to be supplied, a digital/analog converter (DAC1) with its output coupled to the first terminal, a second terminal (R'0) to which digital data is to be supplied, a digital output circuit (DOB) with its output coupled to the second terminal, and a preparation circuit (PLM, SEL) which is coupled to respective inputs of the digital/analog converter and the digital output circuit. The preparation circuit prepares digital data to be processed (RR) for any one of input of the digital/analog converter and input of the digital output circuit.
