4.4 LED Lights
The MCT8315EVM has 6 status LEDs implemented that provide the status of power supplies and functionalities of the evaluation module. By default, the VM LED and 3.3 V Buck LEDs will light up when the board is powered and the program has been flashed onto the microcontroller. Table 4-1 shows LED descriptions including those that are on during power up in bold and Figure 4-5 shows the locations of the LEDs.
Table 4-1 Description of MCT8315EVM LEDs (default in bold after powerup)
| Designator | Name | Color | Description |
|---|---|---|---|
D1 | Buck Regulator | Green | Internal buck regulator is voltage output |
D2 | nFAULT | Red | Lights up when fault condition has occurred on MCT8315 |
D3 | ALARM | Red | Lights up when alarm condition has occurred on MCT8315 |
D4 | VM | Green | Motor power is supplied to the board |
D6 | MSP_LED1 | Red | Used for UART or debugging |
D7 | MSP_LED2 | Green | Used for UART or debugging |
