0024 36 Bitstring 1 ThreshEfgO Efficiency flag. Observations.
Flag used for adjustment of
thresholds. Serialization note:
There is no serialization for
this byte. OI/NI are used to turn
bits on and off, MVIy is used to
reset the byte. A progressive
system is used such that a missed
update will not matter.
