Note:
1. Pin 60 and pin 61 should be pull low to let P5_BUSMD be latched as “00” and make Port5 be operating in MII
2. Pin 89 (SPDTNP5) should be pull low or floating to set Port5 be operating in 100Mbit/s.
3. Pin 91 (DPHALFP5) should be pull low or floating to set Port5 be operating in full duplex mode.
4. Pin 90 (LNKFP5) should be pull low or floating to set Port5 Link up.
About the PCS mode MII connecting to MAC mode MII, it’s very straightforward. If PCS and MAC follow the MII
standard timing and users notice the PCB layout balance, it should not be an issue for PCS to connect to the MAC.
