MIIM Registers
All the registers defined in this section can be also accessed via the SPI interface. Note: different mapping
mechanisms are used for MIIM and SPI. The “PHYAD” defined in IEEE is assigned as “0x1” for Port 1, “0x2” for Port
2, “0x3” for Port 3, “0x4” for Port 4, and “0x5” for Port 5. The “REGAD” supported are 0x0-0x5 (0h-5h), 0x1D (1dh)
and 0x1F (1fh).

Loop Back
1, Perform MAC loopback, loop back path as follows:
Assume the loop-back is at Port 1 MAC, Port 2 is the
monitor port.
Port 1 MAC Loopback (Port 1 reg. 0, bit 14 = ‘1’)
Start: RXP2/RXM2 (Port 2). Can also start from
port 3, 4, 5
Loopback: MAC/PHY interface of Port 1’s MAC
End: TXP2/TXM2 (Port 2). Can also end at
Ports 3, 4, 5 respectively
Setting address ox3,4,5 reg. 0, bit 14 = ‘1’ will
perform MAC loopback on Ports 3, 4, 5 respectively.
0, Normal Operation.
