Use
The purpose of this call is to read the Battery Management Unit (BMU) variables.
This is an improved version of Portable_ReadBMUVariable, which allows multiple variables to be read at once. Using this call when reading multiple variables may allow the BMU driver to perform a more efficient request.
Rather than returning an error state for the entire operation, a status value is returned individually for each variable.
Notes
The BMU settings can be set by using Portable_WriteBMUVariable.
