I am using STM32h753zi MCU and I am trying to enable RMII_PTP_Synchro in STM32 CubeMX but the option is not able to select. Please give me a guidance. Thankyou.

Hello @AFaya.1​ 

RMII_PTP_Synchro is only active when TIM2/TIM3 has an enabled Slave Mode with ITR4 as trigger source or if FDCAN is enabled.

Best regards,
