    • A system includes a voltage sensing module and a frequency adjustment module. The voltage sensing module is configured to sense a supply voltage of a circuit block, generate a first control signal when the supply voltage is less than or equal to a first voltage, and generate a second control signal when the supply voltage is within a predetermined range of a second voltage. The frequency adjustment module is configured to set a frequency of a clock signal supplied to the circuit block to less than a normal operating frequency of the circuit block when the supply voltage is initially supplied to the circuit block after a power on reset operation and the first control signal or the second control signal is received.
    • 一种系统包括电压感测模块和频率调整模块。 电压感测模块被配置为感测电路块的电源电压,当电源电压小于或等于第一电压时产生第一控制信号,并且当电源电压在预定范围内时产生第二控制信号 的第二电压。 频率调节模块被配置为:当在电源接通复位操作之后将电源电压初始提供给电路块时,将提供给电路块的时钟信号的频率设置为小于电路块的正常工作频率,并且第一 控制信号或第二控制信号被接收。
