(1)
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. Refer to
Formulas for Converting on page C-19 .
(3)
Do NOT continually write parameter data to NVS. Refer to the attention on page 6-1 .
