This controls inversion of the transmit BERT pattern.
Possible values are :
notInverted(1): Pattern is transmitted normally.
inverted(2): Each Mark is replaced by Space and
vice versa.
For predefined BERT patterns, the value for this Object
may not be modified. An implementation may choose to
ignore the value of this object, for BERT patterns other
than 'userPattern'. When the value is ignored, the
object contains the value chosen by the underlying hardware.
This object can not be modified when the BERT is running
i.e cbRowStatus is active(1).
