ICS1890
Link Partner Remote Fault Capable (bit 13)
This bit tries to indicate if the link partner supports indication
of a remote fault. If the ICS1890 observes the link partner
Auto-Negotiating with the Remote Fault bit set, this status bit
will be set to a logic one. Otherwise, this bit will be a logic zero.
Note that a logic zero can not definitively mean that the link
partner does not support remote fault indications.
Reserved (bits 12-11)
These bits are reserved for ICS use. They must only be written
as logic zero. Writing a logic one to any of these bits may
prevent the device from operating normally. The value of
these bits when read is unspecified and may be a logic zero or
one.
Transmitted Remote Fault Status (bit 10)
This bit reflects the current status of the Remote Fault bit in
the Transmitted Link Code Word.This bit is set when bit 4:15
is set or when bit 19:4 is set and the link partner is not
transmitting.
Reserved (bits 9-5)
These bits are reserved for ICS use. They must only be written
as logic zero. Writing a logic one to any of these bits may
prevent the device from operating normally. The value of
these bits when read is unspecified and may be a logic zero or
one.
Power-up Remote Fault (bit 4)
When this bit is set to a logic one, the RF bit in the outgoing
Auto-Negotiation Link CodeWord will automatically be set to
a logic one until receive activity is detected (Normal Link
Pulses, Fast Link Pulses, 100Base-TX data, ...).
Bits Reserved for ICS use (bits 3-1)
These bits are reserved for ICS use. These bits should only be
written as logic zero. Writing a logic one to these bits may
prevent the device from operating correctly. The value of
these bits is unspecified and may be a logic zero or one.
Automatic 100Base-TX Power-down (bit 0)
When this bit is set to a logic one and 10Base-T is selected for
the network connection, the 100Base-TX transceiver will
automatically turn off to save power.
When this bit is set to a logic zero, the 100Base-TX transceiver
will never power-down by itself. The 100Base-TX transceiver
will still power-down when the entire device is isolated using
bit (0:10).
