external clock for STM32G031Kxxx

Hi there,

I am looking at STM32G031Kxxx (32pin LQFP) and am wondering whether it is possible to provide an external high speed clock source to this µC?

The datasheet shows that in this package OSC32_IN and OUT are available, but for the HSE, there is only OSC_IN.

So, a crystal cannot be used, but an external clock should be possible - if needed.

Is my assumption right?

I neglected to point out that only either OSC_IN or OSC32 is available in the 32pin package. Both at the same time are not possible with this package.
