Reset circuit of semiconductor circuit

摘要

A reset circuit of a semiconductor circuit for reliably resetting plural reset target circuits in the semiconductor circuit, even when a surge noise signal having a short pulse length or the like is input to the reset circuit, the reset circuit including a reset signal control circuit for controlling timing of deactivating a reset instruction signal for resetting plural reset target circuits in the semiconductor circuit. Respective reset target circuits are for outputting reset completion signals to the reset signal control circuit when the respective reset target circuits have been reset. The reset signal control circuit also is for deactivating the reset instruction signal when all of the reset completion signals have been activated.
