MII/RMII asynchronous signals are COL, CRS. These signals are applicable in both MII and RMII modes. The asynchronous COL input is synchronized separately to both
The asynchronous CRS input is synchronized to the ETxCLK, and must have a minimum pulse width high or low at least 1.5 times the period of ETxCLK.
MDC/MDIO is a 2-wire serial bidirectional port for controlling one or more external PHYs. MDC is an output clock whose minimum period is programmable as a multiple
