Figure 13. FlexSPIN evaluation software - start window
Moving the mouse cursor over the image, a brief description of highlighted areas appears
on the bottom line. Clicking on some areas, a window appears with the related electrical
schematic.
3.2.1 How to turn-on the VswDrv regulator
The integrated switching regulator controller is able to drive an external FET to implement a
switching buck regulator. This regulator is off when the L6460 is powered up for the first time
and can be enabled via the SPI interface. In the first software window click the L6460
device, the following window appears (Figure 14).
