The B1 mask enable (B1MASKEN) bit selects the use of the B1 byte extracted from the
TTOH port. When B1MASKEN is set to logic 1, the B1 byte extracted from the TTOH port
is used as a mask to toggle bits in the calculated B1 byte (the B1 byte extracted from the
TTOH port is XOR with the calculated B1 byte). When B1MASKEN is set to logic 0, the B1
byte extracted from the TTOH port is inserted instead of the calculated B1 byte.
The B2 mask enable (B2MASKEN) bit selects the use of the B2 bytes extracted from the
TTOH port. When B2MASKEN is set to logic 1, the B2 bytes extracted from the TTOH port
are used as a mask to toggle bits in the calculated B2 bytes (the B2 bytes extracted from the
TTOH port are XOR with the calculated B2 bytes). When B2MASKEN is set to logic 0, the
B2 bytes extracted from the TTOH port are inserted instead of the calculated B2 bytes.
The H1/H2 mask enable (HMASKEN) bit selects the use of the H1/H2 bytes extracted from
the TTOH port. When HMASKEN is set to logic 1, the H1/H2 bytes extracted from the
TTOH port are used as a mask to toggle bits in the H1/H2 path payload pointer bytes (the
H1/H2 bytes extracted from the TTOH port are XOR with the path payload pointer bytes).
When HMASKEN is set to logic 0, the H1/H2 bytes extracted from the TTOH port are
inserted instead of the path payload pointer bytes.
