LU3X34FT
Quad 3 V 10/100 Ethernet Transceiver TX/FX
MII Registers
The LU3X34FT has four independant PHYs in it. Each PHY has its own identical set of registers as tabulated
below. The PHY address differentiates which PHY to be read or written into. The following tables of registers are
applicable to each register.
Table 10. MII Management Registers
Note:
Legends:
RO—Read only
R/W—Read and write capable
SC—Self-clearing
LL—Latching low, unlatch on read
LH
Latching high, unlatch on read
COR
Clear on read

1—PHY reset
0—Normal operation
Setting this bit initiates the software reset
function that resets the entire LU3X34FT
device, except for the phase-locked loop
circuit. It will relatch in autonegotiation
configuration pin values (ANEN, FOSEL,
100FD, 100HD, 10FD, 10HD) and set all
registers to their default values. The soft-
ware reset process takes 25
μ
s to com-
plete. This bit, which is self-clearing,
returns a value of 1 until the reset process
is complete.
