23.6
MII signals use TTL signal levels compatible with devices operating at either 5.0 V or 3.3 V.
23.6.1
The receiver functions correctly up to a E_RxCLK maximum frequency of 25 MHz +1%. There is no
minimum frequency requirement. In addition, the processor clock frequency must exceed twice the
E_RxCLK frequency.
