Switch MAC3/MAC4 SW3/SW4-MII Interface
Table 3 shows two connection manners,
1. The first is an external MAC connects to SW3/SW4-MII PHY mode.
2. The second is an external PHY connects to SW3/SW4-MII MAC mode.
Please see the pins [47, 48] description for detail configuration for the MAC mode and PHY mode of the port 4 MAC4
SW4-MII, the default is SW4-MII with PHY mode. Please see the strap pin P2LED0 and the register 223 bit 6 for the
MAC mode and PHY mode of the port 3 MAC3 SW3-MII, the default is SW3-MII with PHY mode also.
Note
‘x’ is 3 or 4 for SW3 or SW4 in the table.
