Claim:
1. Input-output (IO) circuitry, comprising: monitoring circuitry that determines whether a predetermined threshold number of bits of an IO signal are transitioning from a first logical state to a second logical state; an encoder circuit that generates an encoded IO signal in response to the monitoring circuitry indicating that the number of bits of the IO signal that are transitioning from the first logical state to the second logical state exceeds the predetermined threshold number, wherein transmitting the encoded IO signal requires less power than transmitting the IO signal; and an output port of the IO circuitry that outputs a clock signal in a first mode of the IO circuitry and that outputs an additional IO signal bit that is associated with the encoded IO signal in a second mode of the IO circuitry.
