DESCRIPTION
NRZI Enable
Read/Write 1
When this bit is set, the NRZI encoder and decoder
are enabled. When this bit is clear, NRZI encoding
and decoding are disabled.
When this bit is set, the time-out counter in the
receive descrambler is set to time-out after 2 ms
without IDLES. When clear the counter is set to time-
out after 722
μ
s without IDLES.
When this bit is set, the time-out counter in the
receive descrambler is disabled. When this bit is
clear, the time-out counter is enabled.
This bit defines the mode of the Carrier Sense (CRS)
signal. When this bit is set, CRS is asserted due to
receive activity only. When this bit is clear, CRS is
asserted due to either transmit or receive activity.
This bit defines the mode of Pin LED5. When this bit
is set, pin LED5 indicates the synchronization status
of the 100BASE-TX descrambler. When this bit is
clear, LED5 indicates a collision.

Note:
This bit is disabled, and writes to this bit are
ignored when the National Compatibility Mode bit of
the 10BASE-T Configuration Register (address 1Ch)
is set.
When set, this bit unlocks certain read only control
registers for factory testing. Leave clear for proper
operation.
