A CONTAINER is a 32-bit block of data that contains the data type used by a parameter value. If signed, the value is sign extended. Padding is
used in the CONTAINER to ensure that it is always 32-bits.
(2)
This value is used in the formulas used to convert the parameter value between display units and internal units. See Formulas for
Converting on page C-8.
(3)
Do not continually write parameter data to NVS. See the attention on page 5-1.
