12.3.7.4
MIIC0 – MII Command Register 0
CPU Address: h0603
Accessed by CPU (R/W)
Note
: Before programming MII command: set FEN[6]; check MIIC3, making sure RDY; then program MII
command.
12.3.7.5
MIIC1 – MII Command Register 1
CPU Address: h0604
Accessed by CPU (R/W)

Bit [5]:
Report to CPU
0 – Disable (Default)
1 – Enable
When disable new VLAN port association report, new MAC address report or
aging reports are disable for all ports. When enable, register SE_OPMODE is
used to enable/disable selectively each function.
Bit [6]:
MII Management State Machine
0: Enable (Default)
1: Disable
This bit must be set so that there is no contention on the MDIO bus between
MII Management state machine and MIIC & MIID PHY register accesses.
Bit [7]:
MCT Link List structure
0 – Enable (Default)
1 – Disable
Bits [7:0]:
MII Command Data [7:0]
Bits [7:0]:
MII Command Data [15:8]
Bits [4:0]
REG_AD – Register PHY Address
Bits [6:5]
OP – Operation code
“10” for read command
“01” for write command
