The ZL50407 Fast Ethernet access ports (0-7) support 3 interface options: RMII, MII & GPSI. The table below
summarizes the interface signals required for each interface and how they relate back to the Pin Symbol name
shown in the “Ball Signal Description Table” on page 12. It also specifies whether the internal pull up/down resistor
is present for each pin in the specific operating mode.
Notes :
I – Input
O – Output
U – Pullup
D - Pulldown
