Slide 6 LVC Buses come in two forms, serial and parallel. The data and/or addresses can be sent over 1 wire, bit after bit, or over 8 or 32 wires at once. Always there has to be some way to share the common wiring, some rules, and some synchronization. Slide 6 shows a serial data bus with three shared signal lines, for bit timing, data, and R/W.
