14.10.2
Address 00C4
Local BER Transmit Length Register (LTXBLR) defines how many channels of the BER sequence will be
transmitted during each frame. The minimum length of the BER transmitter is 1 channel. To set a desired BER
length, set LXTBL8-0 bits for the desired length -1 channel. For example, to run a BER test for 32 consecutive
channels, program LTXBL to 000011111
14.10.3
Address 00C5
Local BER Receive Length Register (LRXBLR) defines how many channels of the BER sequence will be received
during each frame. The minimum length of the BER receiver is 1 channel. To set a desired BER length, set
LRXBL8-0 bits for the desired length - 1 channel. For example, to receive a BER test for 32 consecutive channels,
program LRXBL to 000011111
