Abstract
An internal voltage from an internal voltage generating circuit is transmitted to a pad in accordance with a control signal, and a buffer circuit coupled to the pad is set in an inactive state. The pad is connected to an external pin terminal via a bonding wire. Consequently, a semiconductor integrated circuit capable of monitoring and forcedly setting an internal voltage from an outside of the circuit device is realized with a minimum number of pin terminals without increasing the number of external pin terminals.
