).
When this bit is reset, excessive zero detection
is disabled for LIU
n
. When this bit is set, excessive zero detect enable is enabled. Excessive zero detection is only
relevant in single-rail mode with HDB3 or B8ZS encoding.

).
If this bit is set, code violation detection is
disabled for the LIU
n
. If this bit is reset, code violation detection is enabled. Code violation detection is only
relevant in single-rail mode with HDB3 encoding. Note that if the
GC
.CODE register bit is set, it ignored the settings
of this register.
