I have notice some jitter on my MCO clock signal when I set high PF4

which is configured as output push pull.

I have stripped down my code and I noticed that this jitter behavior is

also related to PA3 state (configured as input floating low level) and

CSS enabled.

Have you ever got this problem on your design ?

Your problem looks like a product limitation described in the ST72324 errata sheet. Check the October 2002 errata sheet (Rev. 5.1), paragraph 3.2.4.
