EC_MDC output clock frequency for a specific eTSEC port can be programmed by configuring the MgmtClk bit field of
MPC8536E’s MIIMCFG register, based on the platform (CCB) clock running for the device. The formula is: Platform
Frequency (CCB)/(2*Frequency Divider determined by MIICFG[MgmtClk] encoding selection). For example, if
MIICFG[MgmtClk] = 000 and the platform (CCB) is currently running at 533 MHz, f
