    If you want to load the following
    command/data into each part
    in the chain.

    EXAMPLE:
    Start by setting CS low and
    clocking in the command and
    data that will end up in Device
    3 (16 clocks).
    After 16 clocks, Device 2 and
    Device 3 will both have all
    zeros clocked in from the
    previous part’s shift register.
    Clock-In the command and
    data for Device 2 (16 more
    clocks). The data that was pre-
    viously loaded gets shifted to
    the next device on the chain.
    After 32 clocks, Device 2 has
    the data previously loaded
    into Device 1 and Device 3
    gets 16 more zeros.
    Clock-In the data for Device 1
    (16 more clocks). The data that
    was previously loaded into
    Device 1 gets shifted into
    Device 2 and Device 3 contains
    the first byte loaded. Raise the
    CS line to execute the com-
    mands for all 3 devices at the
    same time.
    After 48 clocks, all 3 devices
    have the proper command/
    data loaded into their shift
    registers.
    * Last device on a daisy-chain may be a single channel MCP41XXX device.
