1. Brown-Out Reset
掉电复位,或电源电压跌落复位, 当输入电压VCC跌到某一门限时芯片复位
The MCU is reset when the supply voltage VCC is below the Brown-Out Reset threshold voltage
and the Brown-out Detector is enabled. The Brown-out threshold voltage is programmable.
2. Totem-pole
推拉输出电路
3. IAR调试出现The stack plug-in failed to set a breakpoint on "main". The Stack window will not be able to display stack contents. (You can change this setting in the Tool>Options dialog box.)的警告,程序能烧进去,但不能调试。
需要 进行如下配置:
iar->options->linker->output->format;
选择 Debug informa

本文详细介绍了MCU的两种重要特性:Brown-Out Reset(掉电复位),当电源电压低于预设阈值时,芯片会自动复位;以及Totem-pole相关知识,探讨了MCU在电源管理和稳定性方面的关键机制。
