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,
