Bit Name
Bit Name
These bits are the data trunk codes that can replace the data of the channel selected by the GSUBST[2:0] bits (b2~0, T1/J1-0CBH,...) or the
This bit is valid in 8-bit-based mode or in 7-bit-based mode selected by the PRBSMODE[1:0] bits (b3~2, T1/J1-0C7H,...).
= 0: Disable the data in the corresponding channel to be tested by the PRBS Generator/Detector.
= 1: Enable the data in the corresponding channel to be extracted to the PRBS Generator/Detector for test (when the PRBSDIR bit (b1, E1-
0C7H,...) is ‘0’); or enable the test pattern from the PRBS Generator/Detector to replace the data in the corresponding channel for test (when the
PRBSDIR bit (b1, E1-0C7H,...) is ‘1’). In 8-bit-based mode, the data refers to all 8 bits. In 7-bit-based mode, the data refers to the 7 MSB.
All the channels that are extracted to the PRBS Generator/Detector are concatenated and treated as a continuous stream in which pseudo random
= 0: No operation.
= 1: The data of the corresponding channel is replaced by the signaling trunk code set in the A, B, C, D bits (b3~0, T1/J1-ID-41~58H).
These bits are the signaling trunk codes that can replace the signaling bits of the channel selected by the GSTRKEN bit (b6, T1/J1-0CBH,...) or the
