4.3 Automatic Power-Saving Operations
The ICS1893BF has power-saving features that automatically minimize its total power consumption while it
is operating. Table 4-1 lists the ICS1893BF automatic power-saving features for the various modes.
4.4 Auto-Negotiation Operations
The ICS1893BF has an Auto-Negotiation sublayer and provides a Control Register bit (bit 0.12) to
determine whether its Auto-Negotiation sublayer is enabled or disabled.
When enabled, the ICS1893BF Auto-Negotiation sublayer exchanges technology capability data with its
remote link partner and automatically selects the highest-performance operating mode it has in common
with its remote link partner. For example, if the ICS1893BF supports 100Base-TX and 10Base-T modes –
but its link partner supports 100Base-TX and 100Base-T4 modes – the two devices automatically select
100Base-TX as the highest-performance common operating mode. For details regarding initialization and
control of the auto-negotiation process, see Section 6.2, “Functional Block: Auto-Negotiation”.

Disable Inter-
nal Modules
In 10Base-T mode, the ICS1893BF
disables all its internal 100Base-TX
modules.
In 100Base-TX mode, the ICS1893BF
disables all its internal 10Base-T modules.

When an STA sets the state of the
ICS1893BF Extended Control Register 2,
bit 19.0 to logic:
Zero, the 100Base-TX modules always
remain enabled, even during 10Base-T
operations.
One, the ICS1893BF automatically
disables 100Base-TX modules while the
ICS1893BF is operating in 10Base-T
mode.
When an STA sets the state of the
ICS1893BF Extended Control Register 2,
bit 19.1 to logic:
Zero, the 10Base-T modules always
remain enabled, even during
100Base-TX operations.
One, the ICS1893BF automatically
disables 10Base-T modules while the
ICS1893BF is operating in 100Base-TX
mode.
