What is the PHY interrupt in the MACB driver used for? I cannot find any specific processing in the vPHY_ISR(void) handler in the MACB driver code, except for the reading of the PHY status register.
I know the interrupt setup can be disabled by changing this constant in conf_eth.h like this:
So what will (not) happen if i disable it? If it is no problem it also saves an IO pin. The same pin can then be used as PHY poweroff instead since it default to that function on the PHY.
I am programming stand alone, not using RTOS
