Automatic Power-Saving Operations
The ICS1892 has power-saving features that automatically minimize its total power consumption while it is
operating.
Table 5-1
lists the ICS1892 automatic power-saving features for the various modes.
5.4
Auto-Negotiation Operations
The ICS1892 has an Auto-Negotiation sublayer. It provides both an input pin, ANSEL (Auto-Negotiation
Select) and a Control Register bit (bit 0.12) to determine whether its Auto-Negotiation sublayer is enabled
or disabled. The ICS1892 HW/SW input pin exclusively selects whether the ANSEL pin (which is used for
the hardware mode) or Control Register bit 0.12 (which is used for the software mode) controls its
Auto-Negotiation sublayer.
When enabled, the ICS1892 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 ICS1892 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 7.2, “Functional Block: Auto-Negotiation”
.
