Abstract:
1. An electrical sensing method for nodes in a daisy chain comprising: (a) receiving a plurality of electrical signals from a preceding node in said daisy chain, wherein said plurality of electrical signals represents a first quantity, said first quantity including each and every one of said plurality of electrical signals, and wherein one of said plurality of electrical signals is a least significant electrical signal, and wherein except for said one of said plurality of electrical signals another one of said plurality of electrical signals is a most significant electrical signal; (b) electrically terminating one or more of said plurality of electrical signals, starting said electrical termination at a significant end, wherein said electrically terminated said one or more of said plurality of electrical signals represents a second quantity, said second quantity including each and every one of said electrically terminated said one or more of said plurality of electrical signals; (c) performing a shift of second quantity bit positions on each of said plurality of electrical signals except for said electrically terminated said one or more of said plurality of electrical signals; (d) outputting said shifted each of said plurality of electrical signals except for said electrically terminated said one or more of said plurality of electrical signals at a first set of output positions to a following node in said daisy chain; (e) outputting a third quantity of new electrical signals at a second set of output positions to said following node in said daisy chain, wherein said third quantity is equal in number to said second quantity; and (f) electrically sensing an electrical state of only one of said third quantity of new electrical signals.
