<p>PURPOSE:To enable a microcomputer to control both system resetting and low current consumption mode using one control input terminal, and to eliminate the necessity of using an external control circuit. CONSTITUTION:The microcomputer is provided with a rise input detecting circuit 1 that detects a rise input of control input terminal A and that gives an output signal to a system control circuit 4, and also with an input detecting circuit 2 that detects a fall input of terminal A. Output from the fall input detecting circuit 2 is inputted to a standby control circuit 5 via noise removal circuit 3. Standby control circuit 5 is provided with a control signal from a system control circuit 4.</p> |
