    <description>
    Delay (binary in nanoseconds) from the time the VRM receives the write
    voltage command until the voltage actually moves.   This value is used for
    both increasing and decreasing transitions as part of the overall voltage
    transition time calculation.
    Firmware provides a default value of 8000ns (eg 8us)) if this attribute is
    zero.  Note: the smallest possible delay is limited to 1ns.
