Type (Range0To11[ n ].Type)
This bit indicates which type of value to use for the range comparison in range
n.
This value and Range0To11[
n].ToThisCounter determine the current value that
is used in range comparison as the rate or count value.
Inv (Range0To11[ n ].Invert)
This bit indicates whether the range
n should be active inside or outside the
Range0To11[
n].Low Limit and Range0To11[n].HighLimit window.
• 0 = The range n is active when the rate or count value is at or between
Range0To11[
n].Low Limit and Range0To11[n].HighLimit. When the
range is active, the RangeActive.
n bit is set. When the range is active and
enabled, the outputs indicated in the Range Output Control word
are activated
.
• 1 = The range n is active when the rate or count value is lower than or
equal to Range0To11[
n].LowLimit or higher than or equal to
Range0To11[
n].HighLimit. When the range is active, the RangeActive.n
bit is set. When the range is active and enabled, the outputs indicated in
the Range Output Control word are applied.
IMPORTANT If this value is greater than NumberOfCounters, a configuration error
occurs.
