The TPS65988 firmware implements a host interface over I 2 C to allow for the configuration and control of all device options. Initial device configuration is configured through a configuration bundle loaded onto the device during boot. The bundle may be loaded via I 2 C or SPI. The TPS65988 configuration bundle and host interface allow the to be customized for each specific application. The configuration bundle can be generated through the Application Customization Tool and additional information on the device host interface can be found in the Host Interface Reference Manual.
