Does STM32C071CBT6 support PLL for external oscillator?

[curiocity]

I am using an 8 MHz external oscillator and was planning to use a PLL to increase the system frequency. However, when I open the Clock Configuration tab in CubeMX, I don’t see any option for a PLL.

I’ve also shared a screenshot of the clock configuration where it’s clear that the PLL option is not available.

So my question is: Does the STM32C071CBT6 microcontroller support PLL with an external oscillator?

What makes you think the STM32C071CBT6 has a PLL?

There is no mention in the Datasheet

That would explain why CubeMX doesn't show it

however, there are three mentions in the Reference Manual:

@STTwo-32 These look like copy-paste errors in the RM ?

Hello @Andrew Neil 

I've escalated this to the doc team for review (under internal ticket number 212567).

Best Regards.
