Running Disparity Rules
The SerialLite II rules for running disparity are as specified in Clause 36
of the IEEE 802.3-2002 specification.
Valid and Invalid code-groups
Not every 10-bit value constitutes a valid 10-bit code. The 10-bit space is
only partially populated with valid combinations.
Valid and invalid 10-bit code groups for SerialLite II are as specified in
Clause 36 of the IEEE 802.3-2002 specification. This clause defines both
the data code-group (D code-group) and the special code-group (K
code-group). See
“8b/10b Code Groups” on page 2–75
for a complete list
of these groups.
