No interrupt will be generated because the signal changes are in the negativedirection.sample 6 will generate an interrupt, because the signal value is between High-Value and LowValue and the signal difference in the positive direction comparedto sample 2 is more than DeltaValue.RAPID reference manual - part 1a, Instructions A-R 185
