Refer to Table 12: Embedded reset and power control block characteristics for the values of VPOR/PDR and VPVD. 2.3.13 Voltage regulator The regulator has three operation modes: main (MR), low power (LPR) and power down. ● MR is used in the nominal regulation mode (Run) ● LPR is ...

上电的时候串口会输出usb enter low power mode，说设备进入的低电压模式
standby模式1.9uA,PWR_EnterSTOPMode(PWR_Regulator_LowPower,PWR_STOPEntry_WFI); stop模式:11uA,PWR_EnterSTANDBYMode(); 实验证明,将IO端口设成IPU/IPD/AIN/PPOUT=1/PPOUT=0/ODOUT=0,电流是基本相同的,最可怕的就是GPIO浮空,且电路上未外接上拉下拉,这样电流就会比较大。 原来以来PPOUT要是输出为0,就...
1. 确保在切换时钟源之前，等待LSE稳定。您可以通过检查BDCR寄存器中的LSERDY位来确认LSE是否已稳定。``...
