The MCT8316AEVM includes the MSP430FR2355 low-power MCU (as shown in Figure 4-4) to communicates via I2C with the MCT8316A.

In order to program the MSP430FR2355, an external MSP430 FET programmer must be connected to the Spy-Bi-Wire (SBW) interface connector J4. Many MSP430 LaunchPad™ provide an onboard eZ-FET Debug Probe that can be jumper-wired to the MCT8316AEVM to flash the firmware into the MSP430FR2355 microcontroller.

The user can use the Reset (RST) button at any time to reset and restart the MCU program. Two active-low LEDs, D6 and D7, can be used for debug purposes as well.

Finally, a shunt jumper bridge on the 32-pin connector J6 ties all signals between the microcontroller and MCT8316A. These jumpers can be inserted or removed as needed in order to isolate the microcontroller from the gate driver. This allows for microcontroller signal debugging or using the MCT8316AEVM as a standalone gate driver with an external microcontroller.
