When this bit is set, the descrambler will be loaded
with the value in the Descrambler Initialization Key
field. When the load is complete, this bit will clear
automatically.
These bits should be read as don’t cares and, when
written, should be written to 0.
This register allows the Descrambler to be loaded
with a user-definable key sequence. A value of 000h
has the effect of bypassing the descrambler 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.
