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.

SBER
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.
Note: [n] denotes input stream from 0 - 31

Stream[n] BER Count Bits (Read Only)
The binary value of these bits refers to the bit error counts. When it reaches its maxi-
mum value of 0xFFFF, the value will be held and will not rollover.
Note: [n] denotes input stream from 0 - 31
