STM32G474: What are the available GPIO OSPEED frequencies?

[TwelveSquared]

I can't seem to find this in the datasheet or reference manual. The GPIO OSPEED register is documented as 00: Low speed, 01: Medium speed, 10: High speed, 11: Very high speed. But what are the actual frequencies? I can't seem to locate the information after looking for it for some time.

In the reference manual:

> Note: Refer to the device datasheet for the frequency specifications and the power supply

> and load conditions for each speed..

In the datasheet "Table 59. I/O (except FT_c) AC characteristics(1) (2)" lists the values you're after.

Thank you! That is exactly what I was looking for.
