in the Registers screen. See the BQ76922 data sheet and supporting documentation for register information.
When a configuration file is available it may be imported to set all operational selections at once. However,
a configuration file loaded with Data Memory Import can load as little as 1 parameter, so the user should be
familiar with the contents of imported files. With a new device or after loading a configuration file, individual
register changes may be made. Configuration register programming typically involves the following general
principles selected in various register names:
1. Selection of the function for multi-function pins
2. Selection of the protection features to be enabled
3. Selection of the protection thresholds for the enabled features
4. Setting the FET control options
5. Exporting (saving) the configuration register file for future use
When no additional changes are anticipated to the configuration and extended validation is planned, the user
may write the configuration to OTP. OTP is written using the
Program OTP button on the Data memory window
of BQStudio. Once programmed the device loads the register values from OTP after reset. Additional register
changes may be made, but the user should realize the part features have been permanently changed. OTP
settings may be incompatible with additional hardware configuration changes and could result in damage. The
user should check settings or replace the IC or EVM as required.
CAUTION
Hardware changes after OTP programming may result in damage to the IC or board after reset if
incompatible configuration is selected.
