The TRMP Error Insertion register controls the transmit regenerator and Multiplexer diagnostic
features.
These register bits are valid for both master and slave slices. Please refer to individual bit for
details.
B1MASKEN
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.
This bit is only valid for master slices.
B2MASKEN
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.
