Question
Where to route the external ETH PHY interrupt signal, so it would be used as sub-interrupt in the MAC peripheral?
The part I am using it the STM32H753II. Trying to use the MAC peripheral I got stuck at PYH interrupt, for which is stated to be included as one of the sub-interrupts of the module (last bullet of 58.8.3). The corresponding mask and status bits are well documented in register description (58.11.4). I have trouble finding information about the way this signal is routed into the device. The PHY interrupt signal is declared as one of the interface signals (58.3), however I fail to find a mapping to the pin of the device, or some other way to define it.
