• When the TESTEN bit is enabled and the PRBSDIR bit is ‘0’, the
received data will be extracted to the PRBS Generator/Detector.
The received data can be extracted in unframed mode, in 8-bit-
based mode or in 7-bit-based mode. This selection is made by the
PRBSMODE[1:0] bits. In unframed mode, all the received data
stream is extracted and the per-channel/per-TS configuration in
the TEST bit is ignored. In 8-bit-based mode or in 7-bit-based
mode, the received data will only be extracted on the channel/
timeslot configured by the TEST bit. Refer to Chapter 3.27.1 PRBS
Generator / Detector for details.
