Abstract
Operating a demultiplexer on an IC bus, the demultiplexer including a set of input signal lines from an IC master and a plurality of sets of output signal lines, the demultiplexer configured to couple the inputs among the output in dependence upon a demultiplexer select signal line that couples the demultiplexer to a rise time detection circuit, where the rise time detection circuit is also coupled to the input signal lines and the rise time detection circuit: monitors a voltage of at least one of the input signal lines, including: receiving, from the IC master, a signal on one of the lines; and detecting rise time of the signal; and if the rise time of the signal is less than a predefined threshold, configuring the demultiplexer to vary the coupling of the input signal lines from a first set of outputs to a second set.
