Bit Error Rate Counter Clear: When this bit is high, it resets the internal bit error
counter and the content of the bit error count register (BCR) to zero. Upon completion of
the reset, set this bit to zero.
Bit Error Rate Test Start: When this bit is high, it enables the BER transmitter and
receiver; starts the bit error rate test. The bit error test result is kept in the bit error count
(BCR) register. Upon the completion of the BER test, set this bit to zero.
Memory Block Programming Enable: When this bit is high, the connection memory
block programming mode is enabled to program Bit 0 to Bit 2 of the connection memory.
When it is low, the memory block programming mode is disabled.
Output Stand By Bit: This bit enables the STo0 - 15 and the STOHZ 0 -15 serial out-
puts. The following table describes the HiZ control of the serial data outputs:
Memory Select Bit. These bits are used to select connection memory or data memory:
