The bit band feature is no available internally inside the Cortex-M7 processor. How can I set/reset bit as convenient as bit-banding?

Hello ,

Hope you are doing well.

You are correct bit-banding is not supported by Cortex M7 cores. There is not an equivalent of this on Cortex-M7. I would recommend to check the following links as there are some recommendations that may help you.

Unsupported Cortex-M4 features
