Reserved. In normal functional mode, these bits MUST be set to zero.
Stream[n] Bit Error Rate Counter Clear: When this bit is high, it resets the internal
bit error counter and the stream BER Receiver Error Register to zero.
Stream[n] Bit Error Rate Test Start: When this bit is high, it enables the BER
receiver; starts the bit error rate test. The bit error test result is kept in the BER
Receiver Error (BRER[n]) register. Upon the completion of the BER test, set this bit to
zero. Note that the RBEREB bit must be set in the IMS Register first.
Stream[n] BER Count Bits (Read Only): The binary value of these bits refers to the
bit error counts. When it reaches its maximum value of 0xFFFF, the value will be held
and will not rollover.
