&par Example Description

This example demonstrates how to output the main system clock (PLL output) via 
the MCO (Microcontroller Clock Output) function on pin PC12 for monitoring or further use.
This example can be used to quickly verify the correctness of the clock configuration and 
can also serve as a clock source for other subsystems, enhancing system flexibility and scalability.

&par Hardware Description
