LPC54606 usage with KSZ8091RNB

We are plannig to develop a board using 100-pin LPC54606 and add ethernet communication with KSZ8091RNB RMII phy.


We already have a similar product using LPC4078 processor, however, I notice that RMII pins are different on these processors. For LPC4078 we use the CRS_DV MAC pin, witch is missing on LPC546x. We also tried out to use RX_DV pin for this function on LPC4078 without success.


It is possible to use LPC546x in RMII mode? We are not sure about using the RX_DV pin for the same role of CRS_DV.


Best regards,
