1. Guaranteed by design.

2. The frequency of the GPIOs that can be supplied in VBAT mode (PC13, PC14, PC15 and PI8) is limited to 2 MHz

3. The maximum frequency is defined with the following conditions:

(tr+tf) ≤ 2/3 T

Skew ≤ 1/20 T

45%<Duty cycle<55%

4. The fall and rise times are defined between 90% and 10% and between 10% and 90% of the output waveform, respectively.

5. Compensation system enabled.
