ABSTRACT:
A remote controller includes an oscillation circuit for generating a basic clock signal; a read only memory for storing program data; a central processing unit electrically connected to the oscillation circuit and the read only memory for fetching output data from the read only memory and generating a remote control signal; a key matrix; a key source circuit connected to the key matrix; a key return circuit connected to the key matrix; and a reset circuit electrically connected to the central processing unit, the oscillation circuit and the key return circuit. The reset circuit places at least the central processing unit in a reset state after power has been input and if any key input appears on the key matrix, and then releases the central processing unit from the reset state before having the central processing unit return to the reset state.
