STM32F031G6U TIM14 supports OPM (One Pulse Mode)?

[TwelveSquared]

STM32CubeMX (STM32Cube_FW_F0_V1.11.2) allows option for One Pulse Mode for TIM14. Does TIM14 actually support OPM on STM32F031G6U? In Reference Manual (RM0091 rev 9), TIM14_CR1 does not have bit 3 OPM. Is mistake in Reference Manual or in STM32CubeMX?

Hello,

In page 468 OPM is mentionedAlso in page 474

I don't have a 'F031 but just tried on a 'F091 and yes, it does have OPM in TIM14, while the same RM0091 applies to it.

But try yourself with the 'F031, it's easy, you can do it in the debugger, you don't need to write a single line of code.

I'd say, documentation bug.

@Imen DAHMEN​ , can you please have a look at this?

Thanks,

In that case, there must be a mistake in the reference manual, in the TIM14_CR register definition page, that should bit 3 be defined as OPM. I hope someone from STmicro will notice this and report it to the documentation team.
