Connection of unused crystal pins of microcontroller

[24vtingle]

Hi,
We are using the STM32L073 micro

https://www.st.com/en/microcontrollers-microprocessors/stm32l073rz.html

We are using the 32.768MHz crystal pins with a 32.768MHz crystal. Do you know to what we should connect the 4MHz crystal pins or just leave them open?
(Because we dont use a 4MHz crystal)

Guess you are talking about 32 kHz rather than 32 MHz crystal.

Crystal pins are also GPIO and can be treated as any other unused pins. Avoid floating state, enable either pull-up/pull-down or drive it as outputs.
