Hi,
Is it possible to use GREFCLK instead of REFCLKA for RMII interface (TC38xx)?
P11.5 instead of P11.12?
Thank you for your help

Hi ub786,
From the user manual TC3xx and TS appx, you can find EPR field 100b leads that RMII is selected and an internal predivider divides the clock clk_rmii_i from pin ETHRXC by 2 or 20 and provides it to the internal signals clk_tx_i and clk_rx_i. And clk_rmii_i is 50-MHz clock used by the RMII from PHY.
