ICS1893Y-10 Rev F 1/20/04
The Node/Repeater Configuration bit directly indicates the state of the NOD/REP input pin. When this bit is
logic:
•
•
There are two primary differences between Node mode and Repeater mode.
•
•
The Hardware/Software Priority Status bit directly indicates the state of the HW/SW pin. When this bit is
logic:
•
•
The ISO/IEC specification defines bit 5.13 as the Remote Fault bit, and bit 19.13 is functionally identical to
bit 5.13. The Remote Fault bit is set based on the Link Control Word received from the remote link partner.
When this bit is a logic:
•
•
See
Zero, the NOD/REP input pin is pulled down, which instructs the operation code to operate in Node
mode.
One, the NOD/REP input pin is pulled up, which instructs the ICS1893Y-10 to operate in Repeater mode.
In Node mode:
In Repeater mode:
Zero, the hardware pins have priority over the (software) register bits for establishing the ICS1893Y-10
configuration.
One, the (software) register bits have priority over the hardware pins for establishing the ICS1893Y-10
configuration.
Zero, it indicates the remote link partner does not detect a Link Fault.
One, it indicates to an STA that the remote link partner detects a Link Fault.
– The SQE Test default setting is enabled.
– The Carrier Sense signal (CRS) is asserted in response to either transmit or receive activity.
– The SQE Test default setting is disabled.
– The Carrier Sense signal (CRS) is asserted in response only to receive activity.
