12.1 Manufacture Testing
To improve the manufacture testing flow, the bq78350-R1 allows certain features to be toggled on or off
through ManufacturerAccess() commands: for example, the PRE-CHG FET(), CHG FET(), DSG FET(),
Lifetime Data Collection(), Calibration(), and so on. Enabling only the feature under test can simplify the
test flow in production by avoiding any feature interference. These toggling commands will only set the
RAM data, which means the conditions set by the these commands will be cleared if a reset or seal is
issued to the gauge. The ManufacturingStatus() keeps track of the status (enabled or disabled) of each
feature.
The data flash Mfg Status Init provides the option to enable or disable individual features for normal
operation. Upon a reset or a seal command, the ManufacturingStatus() will be re-loaded from data flash
ManufacturingStatus. This also means if an update is made to ManufacturingStatus() to enable or
disable a feature, the gauge will only take the new setting if a reset or seal command is sent.
