Oscillators with STM32C071RBT6

[AndrewFFFF]

Hello to everyone

I'm using the board NUCLEO-C071RB. I already done the firmware, and it seems work fine.

Because now i must build my board i check again my project:

I forgot to set PF0-PF1 (Osci IN OUT) and PC14-PC15(OSCX IN OUT). It would huge problem so why does the MCU work fine?

The chip will default to using an internal oscillator.
