Internal MAC clock frequency for Ehernet of i.MX6

Dear All,

I want to set frequency of MII clock(MDC pin).

I refer to the following point.

IMX6DQRM.pdf (Rev2)
- 23.5.7 MII Speed Control Register (ENET_MSCR) (P.1100)
- Table 23-12. Programming Examples for MSCR (P.1100)

Internal MAC clock frequency is listed in Table 23-12.
However, I do not know which this frequency shows.

Is this frequency set in DIV_SELECT Field of CCM_ANALOG_PLL_ENETn registers?

May I have advice?

Best Regards,
Yuuki
