Datasheet
Table 8 summarizes the relationship between input voltage levels (VMF1, VMF2, VMF3, VMF4) and
the configuration function for each of the MF input pins. Each MF pin shows two configuration
inputs; configuration function and MII address. The initial setting of the corresponding bit is also
shown.
Table 8.
MF Pin Function Settings1, 3
Input Voltage Levels2

Function
VMF1 (5V)
VMF2 (3.5V)
VMF3 (1.5V)
VMF4 (0V)
MF0
MII Address Bit 0
1100
Auto-Negotiation
Sets the initial value of bit
0.12
Disabled
(0.12 = 0)
Enabled
(0.12 = 1)
Enabled
(0.12 = 1)
Disabled
(0.12 = 0)
MF1

Repeater / DTE Mode
Sets the initial value of bit
19.13

MF4
MII Address Bit 4
1100
If Auto-Negotiate Enabled via
MF0, MF4 works in combination
with CFG1 to control operating
speed and duplex advertisement
capabilities via bits 4.5 - 4.8.
See Table 9 for details.
If Auto-Negotiate Disabled via
MF0, MF4 selects either
TX or FX Mode
Sets the initial value of bit
19.2
100TX
(19.2 = 0)
100FX
(19.2 = 1)
100FX
(19.2 = 1)
100TX
(19.2 = 0)
1. In MDIO Control Mode, the MF pins control only the initial or default value for the respective register bits. In Manual Control
mode, the MF pins provide continuous control of the respective register bits.
2. Input Voltage Levels (VMF1, VMF2, VMF3, VMF4) for MF pins.
3. See Table 12 through Table 14 for operating configuration set-up.
