Bit 2: Transmit BERT Port Direction Control (TBPDIR).
Bit 1: Transmit BERT Port Framed/Unframed Select (TBPFUS).
Bit 0: Transmit BERT Port Enable (TBPEN).
0 = Normal (line) operation. The transmit BERT port sources data into the transmit path.
1 = System (backplane) operation. The transmit BERT port sources data into the transmit path (RDATA).
In this mode the data out of the transmit BERT is muxed into the receive path at RDATA (the line side of
the elastic store).
0 = The transmit BERT will not clock data into the F-bit position (framed)
1 = The transmit BERT will clock data into the F-bit position (unframed)
0 = Transmit BERT port is not active
1 = Transmit BERT port is active
