2.3 Status LEDs (D3, D5, D6) and Subregulator

The switch S1 enables and disables the onboard 3.3V regulator: U5. When the subregulator is enabled, the green LED D3 illuminates. The subregulator must be enabled for normal operation of TMP9R01EVM as the subregulator supplies power to the device and pullup voltage of the communication lines.

The red LED D4 is the MSP430F5528 status LED. The different modes of operation are displayed by the LED status and are shown in Table 2-1.

Two additional LEDs are presented on the EVM. The D5 LED can indicate a THERM fault and turns on when the device detects a THERM fault and brings the pin LOW. D6 does the same function but for the ALERT/THERM2 pin. Both these LEDs are red.
