Hi.

I would like to ask if speed setting of a pin in GPIO->OSPEEDR register is relevant also if a pin is configured in input/alternate mode? Or is this setting relevant only for output mode?

I am asking specifically for SPI clock pin, which has an alternate function mode. Should I set it to high speed or leave it on default low speed?

Thanks
