Configuration and Monitoring
Set BTCR.BERTE = 1 to enable the BERT. The following tables show how to configure the on-board BERT to send
and receive common patterns.

After configuring these bits, the pattern must be loaded into the BERT. This is accomplished via a zero-to-one
transition on BCR.TNPL and BCR.RNPL
Monitoring the BERT requires reading the BSR register, which contains the Bit Error Count (BEC) bit and the Out
of Synchronization (OOS) bit. The BEC bit will be one when the bit error counter is one or more. The OOS will be
one when the receive pattern generator is not synchronized to the incoming pattern, which will occur when it
receives a minimum 6 bit errors within a 64-bit window. The Receive BERT Bit Count Register (RBCR) and the
Receive BERT Bit Error Count Register (RBECR) will be updated upon the reception of a Performance Monitor
Update signal (e.g., BCR.LPMU). This signal will update the registers with the values of the counters since the last
update and will reset the counters.
