RMII Support

hey,

i want to use 2 RMII channels in MIMXRT1061CVJ5A.

does pin GPIO_B1_00 for example suitable as RX_ER for RMII mode in channel 2?

as you can see here:

in channel 1, written so its clear that the io support both modes.

same as EX_ER, the question is about all this pins:

  • REF_CLK - GPIO_B0_15(ALT9).
  • MDC & MDIO - GPIO_B0_00 & GPIO_B0_01  (ALT8).
  • TX0+1 - GPIO_B1_14 & GPIO_B1_14, 2  (ALT8).
  • RX0+1 - GPIO_B1_02& GPIO_B1_01, 2 . (ALT8).
  • CRS - GPIO_B0_10 (ALT8).
  • RX_ER -GPIO_B1_00.(ALT8).
    • TX_EN - GPIO_B0_14. (ALT8).

thank you!
