Reserved. In normal functional mode, this bit MUST be set to zero.
Backplane BER Receive Stream Address Bits: The binary value of these bits
refers to the backplane input stream which receives the BER data.
Backplane BER Receive Channel Address Bits: The binary value of these bits
refers to the backplane input channel in which the BER data starts to be compared.
Reserved. In normal functional mode, these bits MUST be set to zero.
Backplane BER Length Bits: The binary value of these bits refers to the number of
channels, the BER data will last. The maximum number of backplane BER channels
is 511.
Backplane Bit Error Rate Count: The binary value of these bits refers to the back-
plane bit error count.
