Question
STM32 RMII Reference Clock
We have a current application in which our F7 is connected to an external Microchip PHY which provides a 50 MHz reference clock for RMII. We are attempting to place the system into a low power mode in which we disable the PHY thus stopping the reference clock. Is there a way to do this that will not cause the network stack on the MCU to fail? We are using Zephyr as our RTOS which may or may not be relevant.
