STM32CubeMX 5.0.1: TIM15 missing "Combined channels = XOR ON" setting
MCU: STM32F303RETx
Firmware: STM32Cube FW_F3 V1.10.0
In TIM15 -> Mode -> Combined Channels it is not possible to select XOR input on TI1:

In the reference manual (RM0316) at page 685 you can see the XOR input:

And at page 720, the register TIM15_CR2[TI1S] description:
So I suppose that there really is the possibility of activating the XOR input for TI1 of TIM15, but the possibility of doing it in STM32CubeMX is missing. Maybe a BUG?
