The system clock (MCK) is divided down to generate MDC (the clock for the MDIO). To conform with IEEE standard 802.3
MDC must not exceed 2.5 MHz. At reset this field is set to 10 so that MCK is divided by 32.
• RTY: Retry Test
When set, the time between frames is always one time slot. For test purposes only. Must be cleared for normal operation.
• RMII: Reduce MII
When set, this bit enables the RMII operation mode. When reset, it selects the MII mode.
