<p>PURPOSE:To start an action with a CPU even when a resetting signal is continuously sent by providing a means to automatically release a resetting condition after a prescribed time. CONSTITUTION:When a resetting signal 21 is inputted from an external circuit, a counter 4 enters a counting condition and a CPU 8 becomes a resetting condition. Here, when the resetting signal 21 is quickly recovered, the counter 4 becomes the resetting condition, the resetting condition of the CPU 8 is released and an action is started. However, when the resetting signal 21 is continuously inputted by the nonconformity of an external circuit, etc., the counter 4 continues a counting action. When an output terminal Q4 becomes an H level, the resetting condition is released and the action of the CPU 8 is started.</p> |
