1 FEC_COL has the same timing in 10-Mbit 7-wire interface mode.
3.7.9.2
MII Serial Management Channel Timing (FEC_MDIO and FEC_MDC)
The MDC frequency is designed to be equal to or less than 2.5 MHz to comply with the IEEE 802.3
standard MII specification. However the FEC can function correctly with a maximum MDC frequency of
15 MHz.
