Function
These flags indicate whether the PV is within any of the eight
ranges when high-speed counter 1 is being operated in range-
comparison mode with upper and lower limits. The In-range
Flags, however, will be ON whenever the comparison value is
within the range regardless of the whether the high-speed counter
is set to execute the interrupt task when the range is entered or
left.

This flag indicates whether a comparison operation is being exe-
cuted for high-speed counter 1.
OFF: Stopped, ON: Comparing
