WebYep, ETH_RMII_REF_CLK is the input for the 50Mhz clock for the STM32 MAC. In normal RMII mode, the same clock has to be applied on PHY REF_CLK input. When using the ''25MHz Mode'' (or ''REF_CLK out mode'', or whatever you call it) the PHY can generate the 50Mhz clock which has to be connected to STM32 ETH_RMII_REF_CLK, of course.
