Question

CubeMX 4.27.0 RCC_OSC_OUT assigned in HSE Bypass mode on F769ii

My reading of the specs for the F7 series is that if an external clock is supplied to RCC_OSC_IN and HSE Bypass mode is selected then RCC_OSC_OUT is available as a general GPIO pin.

CubeMX seems to want to assign it so I loose a pin!!

Should generally be usable, but might behave oddly with code that doesn't understand/use BYPASS, perhaps the System Loader?

I have concerns with L0 parts, a 32 MHz input clock does not permit BYPASS mode, where as an 8 MHz one works as expected.
