SW reset
R/W
1 = reset MC sub-layer, MACs of both PHY ports and switch fabric to
their default states. This bit is self-cleared after an ‘1’ is written to
it.
0 = normal operation
0
3
Remote
Command
Enable
R/W
1 = enable “Remote Command” access at Center side and Terminal
side
0 = disable “Remote Command” access at Center side and Terminal
side
0
2
Enhanced
ML_EN
R/W
1 = defined as follows:
In Terminal side MC mode, if a link down is detected on the fiber
or the Center side UTP, the Terminal side will disable the TX on
its
UTP and turn off the LEDs to its UTP.
In Center side MC mode, this bit has no meaning.
0 = normal operation
ML_EN pin
value during
reset
1
P1 TX_DIS
R/W
1 = disable (tri-state) transmit to Fiber PHY (port 1)
0 = normal operation
0
PHY reset
R/W
1 = reset the PHY of both PHY ports to their default states. This bit is
self-cleared after an ‘1’ is written to it.
0 = normal operation
Note: MC (maintenance) sub-layer registers are not reset by this bit.
1
(Powered
on value in
Center side
MC mode.
After reg.
0x40h is
program-
med, this bit
will be
cleared.)

0
(Default
