Note: This register enables the LIU1-LIU8 BERT. The BERT can only connect to one LIU at a time. The LIU1-LIU8 BERT operates
independently of the LIU9-LIU16 BERT.
Bits 7 to 5: Bit Error Rate Transceiver Select [2:0] (BTS[2:0]). These bits BTS[2:0] select the LIU that the BERT
applies to (see Table 6-18). This is only applicable if the BERTE bit is set.
Bit 0: Bit Error Rate Tester Enable (BERTE). When this bit is set and 2
s have past, the BERT will be enabled.
The BERT register set should be written and read to only after being enabled. The BERT is only active for one LIU
at a time selected by BTS[2:0]. If the BERT is enabled on the transmit (line) side, the BERT data will be
automatically B8ZS/HDB3 encoded before it is transmitted.
