There are LED indicators on both the LAUNCHXL-F280049C and DRV8311HEVM when power is provided and
the micro USB cable is plugged in to the LaunchPad.
The DRV8311HEVM has 4 status LEDs on the board. By default, the VM and 3V3 LEDs will light up when the
board is powered on. The fault LED will light up when the driver reports a fault, and the MCU LED (tied to
GPIO59) can be used for debugging and validation.
Table 4-1 shows the LED descriptions, with the LEDs that
are on during power up indicated in bold. Figure 4-4 shows the LED locations on the EVM.
