External clock source characteristics

High-speed external user clock generated from an external source

In bypass mode the HSE oscillator is switched off and the input pin is a standard GPIO.

The external clock signal has to respect the I/O characteristics in Section 6.3.14. However,

the recommended clock input waveform is shown in Figure 11: High-speed external clock

source AC timing diagram.
