1. A semiconductor chip, comprising:
a transmitter connected to a receiver by plural wires,
wherein the transmitter is configured to send to the receiver on at least one but not all of the wires a first wave form having first and second consecutive signal transitions with a first duration between the first and second signal transitions, wherein the first duration represents a first particular multi-bit data value;
wherein the transmitter is further configured to send to the receiver on at least one other of the wires a second wave form having first and second consecutive signal transitions with a second duration between the first and second consecutive signal transitions of the second wave form, wherein the second duration represents a second particular data value; and
wherein the first particular multi-bit data value is representative of a first portion of a combined data value and the second particular data value is representative of a second portion of the combined data value, and wherein the second portion follows the first portion.
