4.3 Automatic Power-Saving Operations
4.4 Auto-Negotiation Operations
ICS1893CF, Rev. K, 05/13/10
The ICS1893CF has power-saving features that automatically minimize its total power consumption while it
is operating.
Table 4-1. Automatic Power-Saving Features, 10Base-T and 100Base-TX Modes
The ICS1893CF 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 ICS1893CF 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 ICS1893CF 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
