PURPOSE: A micro controller for compact disk player system is provided to decrease the number of pins by outputting output signals for controlling other operations according to each operation using one pin. CONSTITUTION: A micro-controller(100) outputs control signals(CLMTR,OPMTR) for controlling a motor control circuit(200) and signals(DATA,CLK,LAT) provided to a DSP/SSP(300). The motor control circuit(200) responds to control signals(CLMTR,OPMTR) and controls a motor for switching a deck door of a CDP system. The DSP/SSP(300) responds to signals(DATA,CLK,LAT) outputted from the micro-controller(100) and receives a data (DATA). The CDP system has one pin in which control signals(CLMTR,OPMTR) and the data (DATA) are inputted.
