Description
The value 2'b01 indicates a data word. The value
2'b10 indicates a control word.
A logic low indicates that built-in disparity
generator block in the Enhanced PCS maintains
the running disparity.
Description
The value 2'b01 indicates a data
word. The value 2'b10 indicates a
control word.
A logic low indicates that the built-
in disparity generator block in the
Enhanced PCS maintains the
Interlaken running disparity. In the
current implementation, this bit is
always tied logic low (1'b0).
A logic high (1'b1) indicates the
payload word location in a
metaframe.
A logic high (1'b1) indicates the
synchronization word location in a
metaframe.
A logic high (1'b1) indicates the
scrambler word location in a
metaframe.
