Table 28 - BER Receiver Length Register [n] (BRLR[n]) Bits
Table 27 - BER Receiver Start Register [n] (BRSR[n]) Bits
Reserved
In normal functional mode, these bits MUST be set to zero.
Stream[n] BER Receive Start Bits
The binary value of these bits refers to the input channel in which the BER data starts
to be compared.
Reserved
In normal functional mode, these bits MUST be set to zero.
Stream[n] BER Length Bits
The binary value of these bits refers to the number of consecutive channels expected
to receive the BER pattern. The maximum number of BER channels is 32, 64, 128 and
256 for the data rates of 2.048 Mbps, 4.096 Mbps, 8.192 Mbps and 16.384 Mbps
respectively. The minimum number of BER channels is 1. If these bits are set to zero,
no BER test will be performed.
