Hi,
We're using Nucleo-L4 with X-CUBE-BLE1 Expansion SW with lower mode enabled.
The 32L4 HSE XTAL input is driven by external oscillator.
We would like to disable the external clock during low power mode of 32L4 and enable when 32L4 comes out of low power mode. Is three a way to do this via a GPIO pin of 32L4 ? if so, any guidance will be appreciated.
Thanks.
