Bit 3: Receive Multi-frame Alignment Disable (RMAD) – When 0, multi-frame alignment is performed. When 1,
multi-frame alignment is disabled and the trail trace bytes are stored starting with a random byte.
Bit 2: Receive Expected Trail Trace Comparison Enable (RETCE) – When 0, expected trail trace comparison is
disabled. When 1, expected trail trace comparison is performed. Note: When the RMAD bit is one, expected trail
trace comparison is disabled regardless of the setting of this bit.
Bit 1: Receive Data Inversion Enable (RDIE) – When 0, the incoming data is directly passed on for trail trace
processing. When 1, the incoming data is inverted before being passed on for trail trace processing.
Bit 0: Receive Bit Reordering Enable (RBRE) – When 0, bit reordering is disabled (The first bit received is the
MSB TT.RIR.RTD[7] of the byte). When 1, bit reordering is enabled (The first bit received is the LSB
TT.RIR.RTD[0] of the byte).
