2.3 Programming Process

To simplify the programming procedure and reduce programming time, TI VR13 controller devices combine NVM settings into a small number of registers. All settings in MFR_SPECIFIC commands map into registers USER_DATA_00 through USER_DATA_12. Only a few other registers are required. Program the USER_DATA command with the Block Read/Write command protocol described in the SMBus Specification. Table 4 lists the complete NVM configuration for a single device. All other settings map to USER_DATA commands.

The Fusion Digital Power Designer GUI lets power supply designers configure devices in a graphical environment. The GUI saves these settings in a configuration file or script that you can load on to other devices.
