Can OSC_OUT pin be used as GPIO pin when OSC_IN is used as clock input ?

CubeMx shows that both of OSC_IN/OSC_OUT should used as clock pins with HSE(bypass clock source) options.

Hi

Jeon.IckSeong

,

Which device are you using ?

You should check the

datasheet for your device to be sure about the pins assignment.

Regards

Seems that datasheet wins;)

I was wrong - the CubeMX correctly disables the HSE Bypass once I configure the CLOCK OUT PIN for any other purpose

Chip part number is stm32f767 

and I cannot find description about that in STM32F76x datasheet and reference manual.

What i wanna know is that PH1 can be used as GPIO pin while the PH0 is used as oscillator clock input.

CubeMx says 'NOT' possible.

CubeMx version is 4.20.1.

and Firmware version of STM32F7 is 1.6.1

CubeMX 4.21.0, random F767 device - seems to be possible.
