Notes:
1. P = Power supply.
2. MII Rx Mode: The RXD[3..0] bits are synchronous with RXCLK. When RXDV is asserted, RXD[3..0] presents valid data to MAC through the
3. 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
4. MII Tx Mode: The TXD[3..0] bits are synchronous with TXCLK. When TXEN is asserted, TXD[3..0] presents valid data from the MAC through
5. 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
Gnd = Ground.
I = Input.
O = Output.
I/O = Bi-directional.
Ipd = Input with internal pull-down (40K +/-30%).
Ipu = Input with internal pull-up (40K +/-30%).
Opu = Output with internal pull-up (40K +/-30%).
Ipu/O = Input with internal pull-up (40K +/-30%) during power-up/reset; output pin otherwise.
