Table 6. Control/Status Signals
Signal
Type
I
Description
AUTO_EN[3:0]
Autonegotiation Enable.
When this signal is high, autonegotiation is
enabled. Pulsing this signal will cause autonegotiation to restart. This input
has the same function as register 0, bit 12. This input and the register bit are
ANDed together.
Full-Duplex Mode.
When this signal is set high, the PHY will be in full-duplex
mode. A low on this signal will put it in half-duplex mode. This signal is
ignored when autonegotiation is enabled. This is the same function as
register 0, bit 8. This input and the register bit are ORed together.
Carrier Sense Select.
This signal may be used to select the mode of MCRS
operation. When this signal is pulled high, MCRS will be asserted on receive
activity only. This is the same function as register 29, bit 10. This input and the
register bit are ORed together.
Serial Mode Select.
This signal may be used to set the SERIAL_SEL func-
tion of register 30, bit 1 by pulling it high, if station management is unavail-
able. This input and the register bit are ORed together.
Carrier Integrity Enable.
If this signal is pulled high, it will enable the carrier
integrity function of register 29, bit 3, if station management is unavailable.
This input and the register bit are ORed together.
Encoder/Decoder Bypass.
If this signal is pulled high, it will enable the
encoder/decoder bypass function of register 29, bit 6, if station management
is unavailable. This input and the register bit are ORed together.
Scrambler/Descrambler.
This signal may be used to enable the scrambler/
descrambler bypass function by pulling this signal high, if station manage-
ment is unavailable. This is the same function as register 29, bit 4. This input
and the register bit are ORed together.
Speed.
This signal can be used to select the operating speed and is the
same function as register 0, bit 13:

If this signal is pulled high, it will enable 100 Mbits/s operation.
I
If this signal is pulled low, it will enable 10 Mbits/s operation.
This signal is ignored when autonegotiation is enabled. This signal and the
register bit are ANDed.
Broadcast Address.
This signal, when high, causes the PHY to respond to
broadcast management address.
Management Address [4:2]
. These signals are the MSB bits of the manage-
ment address and are decoded as follows:

FX_MODE[3:0]
I
FX_MODE
. When this signal is high, it puts DNC3X3425 in fiber-optic mode.
This signal is ORed with register 29, bit 0 [29.0].
