I am using a LPC1768 connected to a KSZ8873RLLI 3 port ethernet switch on a custom board. I am using the RMII interface to communicate between the LPC1768 and the KSZ8873. I am struggling to know where to start with the initialisation of the RMII interface on the LPC1768. I have found lpc17xx_emac (in the sample programs that come with LPCXpresso) but am not sure if this is appropriate for these devices, as it refers to TI ethernet chip DP83848C, and am not even sure it uses RMII.
