STM32 Self reset

[LSang.11]

Is there a way to self reset other than watchdog?

Without external pull-up resistance

I want to keep the GPIO high even if the MCU performs a soft reset.

Is there any way?

Yes, please read the reference manual of the respective device for the section Power Reset, which contains all sources for the internal reset.

Call NVIC_SystemReset() for software reset, but no reset will retain the pins settings in GPIO, including pull-ups.
