Segment 32050: Signal Edge Detector

Segment 32050: Signal Edge Detector is the eighth segment of the TIS-100.
==Module Information==
The Signal Edge Detector Segment is meant to detect rising and falling edges in a signal by detecting if the value of the signal has changed by 10 or more. Curiously, the detection output is binary, but there isn't a specific level threshold that determines the change as one might expect in binary transmission. Instead, the segment will output a 1 if the signal changes by 10. The segment denotes the start of a signal by the value 0.
