Hi everyone!

 

In RM0091 i was told that  the stm32f0x8 is some special, it's NPOR pin must be held low until VDD is stable, and when VDD is stable, the reset state can be exited either by putting the NPOR pin in high impedance.

 

Does this mean i should connect this pin pull down to GND, and wait for VDD stable, then set the reigster to make the pin high impedance? But how can the mcu knows VDD is on what status? Is there any other method to handle this pin?

 

Thanks~

Benjamin
