- When control bit RDI enable (RnDIEN) is 0:
J2 Byte
The J2 byte may be used to send a trail trace message. The Trail trace message may be 16 bytes or 64 bytes
in length. The 64 byte RAM segment allocated for the J2 message will be used on a shared basis with the N2
byte according to the following table.
N2 Byte
The N2 byte may be used for a Tandem Connection application. The Tandem Connection feature works in con-
junction with control bits ATnJ2TSZ/BTnJ2TSZ (bit 0, X+063H, X+0D3H) according to the following table.
The bit placement of the transmitted N2 (Z6) byte is as shown below:
(bit 1, X+0D3H)
(bit 0, X+0D3H)
(bit 1, X+063H)
(bit 0, X+063H)

Transmit J2 RAM segment is configured for a 16 byte message. The bytes will be
transmitted starting with an arbitrary address. Please note the TEMx28 does not calcu-
late the CRC-7 for the message, nor does it insert the 1000... pattern transmitted the
message.
Transmit J2 RAM segment is configured for a 64 byte message. The bytes will be
transmitted starting with an arbitrary address.
The J2 byte is transmitted as 00H. The 16 byte message written into the J2 RAM seg-
ment is ignored.
Tandem Connection feature is disabled. The value written to registers X+061H (A side
N2 byte) for the A side, and X+0D1H (B side N2 byte) for the B side are transmitted.
Tandem Connection feature is enabled. The 16 byte trail trace message is written to
registers X+03CH to X+04BH for the A side, and X+0ACH to X+0BBH for the B side.
Tandem Connection feature disabled. The value written to registers X+061H (A side
N2 byte) for the A side, and X+0D1H (B side N2 byte) for the B side are transmitted.
X+061H (A side N2 byte) for the A side, and X+0D1H (B side N2 byte) for the B side is
repeated 16 times as the trail trace message.
Tandem Connection feature is enabled. However, the value written to registers
