Bits 4 to 3: Transmit M2 and M1 Byte Control (TMC[1:0]) – These two bits control the source of the transmit M2
and M1 bytes.
Bits 2 to 1: Transmit F1 Byte Control (TF1C[1:0]) – These two bits control the source of the transmit F1 byte.
Note: If TMC[1:0] is 00 and TF1C[1:0] is 01, the F1 byte will be invalid. If TMC[1:0] is 01 and TF1C[1:0] is 01, both
M2 and F1 will carry the transmit HDLC data link. If TMC[1:0] is 10 and TF1C[1:0] is 01, both M1 and F1 will carry
the transmit HDLC data link. When F1 and M# both carry the transmit HDLC data link, the F1 byte and M# byte in
the same frame may or may not be equal.
Bit 0: Automatic REI Defeat (AREID) – When 0, the REI is automatically generated based upon the parity (BIP-8)
errors detected in the receive PLCP Frame Processor. When 1, the REI is inserted from the G1 register bits
TREI[3:0].

00 = concatenated M1 and M2 (128 kHz) from transmit HDLC controller.
01 = M2 (64 kHz) from transmit HDLC controller; M1 from M1 byte register (PLCP.TM12BR).
10 = M2 from M2 byte register; M1 (64 kHz) from transmit HDLC controller.
11 = M2 from M2 byte register; M1 from M1 byte register
00 = transmit Trail Trace controller.
01 = transmit HDLC controller.
10 = F1 byte register (PLCP.TFGBR).
11 = reserved
