Bit 3: Transmit Multiframe Alignment Insertion Disable (TMAD) – When 0, multiframe alignment signal (MAS)
insertion is enabled, and the first bit transmitted of each trail trace byte is overwritten with an MAS bit. When 1,
MAS insertion is disabled, and the trail trace bytes from the Transmit Data Storage are output without being
modified.
Bit 2: Transmit Trail Trace Identifier Idle (TIDLE) – When 0, the programmed transmit trail trace identifier will be
transmitted. When 1, all zeros will be transmitted.
Bit 1: Transmit Data Inversion Enable (TDIE) – When 0, the outgoing data from trail trace processing is output
directly. When 1, the outgoing data from trail trace processing is inverted before being output.
Bit 0: Transmit Bit Reordering Enable (TBRE) – When 0, bit reordering is disabled (The first bit transmitted is the
MSB TT.TIR.TTD[7] of the byte). When 1, bit reordering is enabled (The first bit transmitted is the LSB
TT.TIR.TTD[0] of the byte).
