2.4 Interfacing DRV8320RS and TMS320F280049C LaunchPad

The DRV8320RS device has 40 pins with different functions. These pins are interfaced with the LAUNCHXL-F280049C, which is mapped appropriately to receive the functionality of the BoosterPack plug-in module. These 40 pins are grouped into 4 ports. Table 2-1 lists the interfacing of these ports with the TMS320F280049C device.
