14.11.3
Address 00CA
Backplane Receive BER Length Register (BRXBLR) defines how many channels of the BER sequence will be
received in each frame. The minimum length of the BER receiver is 1 channel. To set a desired BER length, set
BRXBL8-0 bits for the desired length - 1 channel. For example, to receive a BER test for 32 consecutive channels,
program BRXBL to 000011111
14.11.4
Address 00CB
Backplane BER Start Receive Register defines the input stream and the start channel at which the BER sequence
shall start to be received. The BBSRR register is configured as follows:

Backplane Receive BER Length Bits
The binary value of these bits defines the number of channels in addition to
the Start Channel allocated for the BER Receiver. (i.e., Total Channels =
BRXBL value + 1)
Reserved
Must be set to 0 for normal operation
Backplane BER Receive Stream Address Bits
The binary value of these bits refers to the Backplane input stream
configured to receive the BER data.
Backplane BER Receive Channel Address Bits
The binary value of these bits refers to the Backplane input channel at which
the BER data starts to be compared.
