Hello, We have implemented MDIO(Management Data Input/Output) protocol by bit banging in the STM32 Nucleo-L series board and the corresponding frequency of MDIO is 2.8MHz as of now.

My requirement is to increase this frequency since the MCU (Arm® Cortex®-M33) operates at 110MHz. Kindly, share your inputs ?

L??? try show code ...

such high frequencies are typically generated by hardware peripherals, not by software (bit banging). Search for timer dma pwm or timer dma gpio

Hi @sa.2​ ,

Thank you for being ST Community Member!

I noticed you raised the same questions twice. As our goal is to not have duplicated discussion, we are closing this thread and direct everyone to discuss the questions it further here.
