Functionality
The function compares the integer inputs INT_IN1 and INT_IN2 and activates the
binary output OUTPUT, if INT_IN1 is less than INT_IN2.
If INT_IN1 < INT_IN2, OUTPUT = 1, else OUTPUT = 0.
Logic function blocks do not have the hysteresis feature. Oscillating
outputs should be avoided when comparing analog signals that have
very closely varying values.
