[Karan 123]

Hi,

I am working on STM32G0 Nucleo Board with STM32 Cube IDE 1.3.0

How to configure STM32G071R8 64-Pin LQFP Package

as Input or Output or Interrupt with STM32 Cube IDE 1.3.0 . ?

Is there any special setting ? Which I am missing ?

Change the NRST_MODE option bits to 0b10 using STM32CubeProgrammer to disconnect that pin from internal NRST. See info in the reference manual.

One More question , Is there any way to Program Option Bytes for NRST_MODE  and Program Lock (Read Out Protection Byte ) in .c file ?

[TDK]

Yes, look at HAL_FLASHEx_OBProgram. You need to unlock option bytes first. Should be examples in the CubeG0 repository.

It's also possible to change them during programming via the linker file, but that's a bit more complicated to set up.
