P = Power supply.
Gnd = Ground.
I = Input.
O = Output.
I/O = Bi-directional.
Opu = Output with internal pull-up (40K +/-30%).
Ipu/O = Input with internal pull-up (40K +/-30%) during power-up/reset; output pin otherwise.
Ipd/O = Input with internal pull-down (40K +/-30%) during power-up/reset; output pin otherwise.
RMII Rx Mode: The RXD[1:0] bits are synchronous with REF_CLK. For each clock period in which CRS_DV is asserted, two bits of
recovered data are sent from the PHY.
RMII Tx Mode: The TXD[1:0] bits are synchronous with REF_CLK. For each clock period in which TX_EN is asserted, two bits of data are
received by the PHY from the MAC.
