ENH4MASK
When ENH4MASK is set to logic 1, the H4 value (H4V[7:0]) in the THPP Transmit Z3 and
H4 Register is used as an error mask on the H4 byte passing through THPP. When
ENH4MASK is set to logic 0, the H4 (H4V[7:0]) value from the THPP Transmit Z3 and H4
Register is inserted into the transmit stream.
ENG1REC
The valid high ENG1REC register bit enables the insertion of the RDI-P and REI-P
extracted from a mate RHPP into the transmit stream. When ENG1REC is set to logic low,
the G1 byte source is other than from the mate RHPP.
UNEQ
The unequiped bit (UNEQ) controls the insertion of an all one or an all zero pattern in the
path overhead and in the payload, the fixed stuff bytes are excluded from insertion. When
UNEQ is set to logic one, an all one or an all zero pattern is inserted in the path overhead
and in the payload. When UNEQ is set logic 0, no pattern is inserted.
UNEQV
The unequiped value (UNEQV) bit controls the value inserted in the path overhead and in
the payload. When UNEQV is set to logic 1, an all one pattern is inserted in the path
overhead and in the payload if enable via the UNEQ register bit. When UNEQV is set to
logic 0, an all zero pattern is inserted in the path overhead and in the payload if enable via
the UNEQ register bit.
