When this bit is set, the scrambler will be loaded with
the value in the Scrambler Initialization Key field.
When the load is complete, this bit will clear automat-
ically.
These bits should be read as don’t cares and, when
written, should be written to 0.
This field allows the Scrambler to be loaded with a
user-definable key sequence. A value of 000h has
the effect of bypassing the scrambler function.
This is valuable for testing purposes to allow a deter-
ministic response to test stimulus without a synchro-
nization delay.
Note: This field 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.
