Low-speed external user clock generated from an external source
In bypass mode the LSE oscillator is switched off and the input pin is a standard I/O. The
external clock signal has to respect the Table 57. However, the recommended clock input
waveform is shown in Figure 28.
The characteristics given in Table 40 result from tests performed using an low-speed
external clock source, and under ambient temperature and supply voltage conditions
summarized in Table 16.
