4.4 Interfacing DRV8316xEVM and LAUNCHXL-F280049C LaunchPad ™
The DRV8316xEVM has 40 pins with different functions. These pins are interfaced with the LAUNCHXL-
F280049C LaunchPad development kit and are mapped appropriately to receive the functionalities of the
DRV8316R device. These 40 pins are grouped into 4 ports in respect to the LAUNCHXL-F280049C (J1 to
J4).
Table 4-5 and Table 4-6 list the interfacing of these ports of the DRV8316xEVM headers J3 and J4.
