Status LEDs

The TMP114EVM includes two LEDs, D3 and D4, which indicate the status of the board at any time. The green LED D3, illuminates when power is supplied to the VDD net. The VDD net is connected directly to pin A1 of the TMP114, and externally supplied power should not exceed 1.98 V.

The red LED D4, is a status LED for the MSP430F5528. Table 3-1 summarizes the functions of D4.
