芯片资料里明确说明 "含有上电复位(POR)"?这个复位电路应该跟单独的复位芯片内部电路相同吧?最近看STM32F103的时候发现资料里有明确说明, The device has an integrated Power On Reset (POR)/Power Down Reset (PDR) circuitry. It is always active, and ensures proper operation starting from/down to 2 V. The device remains in reset mode when VDD is below a specified threshold, VPOR/PDR, without the need for an external reset circuit. |
