4.1.5 Commands
The Commands tab is displayed on the right side of the BQStudio window. Buttons in this tab allow reading
various information about the device and certain operations by sending a command to the device. Commands
and returned data are shown in the Log Panel of the tab. The seal function is unusual in general evaluation and
is not recommended during initial evaluation.
Sealing the device without remembering the key reduces the function of the EVM.
4.1.6 Data Memory
The data memory tool is used to configure the device. Configuration files can be saved and loaded later to
resume evaluation. At power up, the device is loaded with factory configurations. Configuration can be entered
in the volatile registers using the Data Memory tool. The Data Memory tool displays as a tab in the center pane
of the BQStudio window.
settings are grouped into different functions accessed with buttons on the left side of the panel. Other functional
sections can be displayed by clicking on the named button.
4.1.6.1 Entering, Saving, and Loading Configuration
Most of the configuration of the BQ76905 is accomplished through setting values in the data memory. The data
memory locations are accessed using the buttons in the Data Memory view. The Parameter View selection at
the top of the panel allows the choice of basic parameters, which shows commonly used parameters, or all
parameters which shows more configuration parameters. Data values can be changed by selecting and entering
a value. Parameter registers, which are bit fields, can be changed by selecting the bit in the pop up when the
register or the value is selected. Data Memory must be written after bit changes, and a button is provided under
the bit field.
Figure 4-6
shows the bit field for the Enabled Protections A, which is one of the most basic settings
that must typically be changed with the EVM.
