    Multiple instances may be daisy chained, which can be configured
    via the number of supported GPIOs.

      Number of pins for the expander. This must be a multiple of 8.
      The number of pins also defines how many devices are daisy chained.
      Set to 8 for one instance without daisy chaining.
