2.3.2 Example NVM Data

Table 4 gives an example configuration that contains all programmable parameters in a VR13 controller device. Every application has different data. All other parameters stored in configuration files are either calculated, measured, or derived from these values. The Fusion Digital Power Designer GUI displays block commands in ascending order of significance (for example byte 0, byte 1, ...). The GUI displays word commands in descending significance (for example byte 1, byte 0).
