I have a question to the note in the datasheet (RM0385 Rev 6, Page 682). Bit 3 OC1PE - Note 2.

What means this note?

"The PWM mode can be used without validating the preload register only in one
pulse mode (OPM bit set in TIMx_CR1 register). Else the behavior is not guaranteed."


We can use the preload only in one pulse mode. Is this correct? How can I validate the preload register?


Best regards,
