WINDOW
This function outputs TRUE when INPUT A is within a programmable range,
and FALSE otherwise.
INPUT B sets the threshold of the window to be monitored. INPUT C defines
the range of the window around the threshold, i.e. if INPUT B = 5 and INPUT C
= 4 then the range is 3 to 7.
If INPUT C is set to zero, the output will only be TRUE if INPUT A is exactly
equal to INPUT B (this is fulfilled in the default condition when inputs A, B & C
are all zero)
If INPUT C is set to a negative value, its absolute value defines the window
range, and the output is inverted.

INPUT A provides a rising edge trigger to increment the output count by one.
INPUT B provides a rising edge trigger to decrement the output count by one.
INPUT C holds the output at zero.
The output starts at zero. The output is limited at ±30000 (±300.00%).
