Bit 3: Receive Multiframe Alignment Disable (RMAD) – When 0, multiframe alignment is performed. When 1,
multiframe 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).

Bits 11 to 8: Expected Trail Trace Identifier Address (ETIA[3:0]) – These four bits indicate the expected trail
trace identifier byte to be read/written by the next memory access. Address 0h indicates the first byte of the
expected trail trace identifier. Note: The value of these bits increments with each expected trail trace identifier
memory access (when these bits are Fh, a memory access will return them to 0h).
Bits 3 to 0: Receive Trail Trace Identifier Address (RTIA[3:0]) – These four bits indicate the receive trail trace
identifier byte to be read by the next memory access. Address 0h indicates the first byte of the receive trail trace
identifier. Note: The value of these bits increments with each received trail trace identifier memory access (when
these bits are Fh, a memory access will return them to 0h).
