电容在上接高电平，电阻在下接地，中间为RST。这种复位电路的工作原理是：通电时，电容两端相当于是短路，于是RST引脚上为高电平，然后电源通过电阻对电容充电，RST端电压慢慢下降，降到一定程序，即为低电平，单片机开始正常工作。
首先RST保持两个机器周期以上的高电平时自动复位
1、上电复位：上电瞬间，电容充电电流大，电容相当于短路，RST端为高电平，自动复位；电容两端的电压达到电源电压时，电容充电电流为零，电容相当于开路，RST端为低电平，程序正常运行。
2、手动复位：首先经过上电复位，当按下按键时，RST直接与VCC相连，为高电平形成复位，同时电解电容被短路放电；按键松开时，VCC对电容充电，充电电流在电阻上，RST依然为高电平，仍然是复位，充电完成后，电容相当于开路，RST为低电平，正常工作。
