Question

STM32CubeIDE no longer generates PLLQ higher than 33MHz for G03X since version 1.15.0

Version 1.15.0 and also 1.15.1 wrongly limit PLLQ to not greater than 33MHz regardless what VCO is.

The reference manual says 128MHz or 32MHz are allowed for high and low VCO. But only 32MHz is allowed for 1.15.0 and later. Older versions do not have this issue.

Version 1.15.1, PLLQ at 128MHz is not allowed.

Version 1.15.0, PLLQ at 128MHz is allowed.
