NOTES:
1 MDC is generated by the MPC5125 with a duty cycle of 50% except when MII_SPEED in the FEC MII_SPEED control register
is changed during operation. See the MPC5125 Reference Manual (MPC5125RM).

2 The MDC period must be set to a value of less than or equal to 2.5 MHz (to be compliant with the IEEE MII characteristic) by
programming the FEC MII_SPEED control register. See the MPC5125 Reference Manual (MPC5125RM).
