Additional characteristics returns an answer in
PWE . If a bit is logic "1", the condition is
LOW
true according to the table below:
If one of bit 0 Special Default Value, bit 1 Special
Upper Limit or bit 2 Special Lower Limit is true, the
parameter has power unit-depending values.
Bit 7 and 8 indicate the attributes for the
LCP access, see table.
Bit 9 indicates No bus Access.
Bits 10 and 11 indicate that this parameter can only be read over the bus.
