よくあるご質問
How long does it take for the Reset Pin to remain low logic to trigger the MCU Reset? 日付：2018-11-27
In the NuMicro® family microcontroller (MCU), MCU Reset through the Reset Pin requires maintaining the Reset Pin at a low logic for a fixed period of time. This time varies slightly depending on the part number in each series, but falls within 20~35 us. Please refer to the Technical Reference Manual (TRM) of each series for detailed time. A detailed description will be given in the System Manager chapter.
For example, in the M031 series, it is necessary to maintain the voltage of the Reset Pin below the level of 0.2 VDD for more than 32 us to ensure that the MCU Reset can be triggered.
