OPTR[9:0]:
The OPTR[9:0] bits are used to set an arbitrary active offset value in the
corresponding outgoing (STM-1) stream. The arbitrary AU3/AU4 pointer value
is transferred by writing to the STP Outgoing Pointer MSB register. A legal
value (i.e. 0 ≤ pointer value ≤ 782) results in new AU3/AU4 pointer(s) in the
