    • 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.
    • 即使当具有短脉冲长度等的浪涌噪声信号被输入到复位电路时,半导体电路的复位电路可靠地复位半导体电路中的多个复位目标电路,复位电路包括一个复位信号控制电路 控制用于复位半导体电路中的多个复位目标电路的复位指令信号的定时。 各复位目标电路用于在复位目标电路复位时将复位完成信号输出到复位信号控制电路。 复位信号控制电路也用于当所有复位完成信号都被激活时,使复位指令信号无效。
