I am struggling getting my head around the input and output logic levels, mostly the output levels of this STM32 (STM32F446xC/E).
This table shows the output logic levels as dependent on if it is a CMOS, TTL, or something else which I don't know what kind of port. But how do I know if it is a CMOS, TTL or anything other? I can't find that information, only that all GPIOs are TTL and CMOS compliant, which I assume has to do with input rather than output.
What will be the output voltage levels? How do I know if my port is CMOS or TTL and thereby know which row of the table to read?
