2.3 Status LEDs and Sub-regulator

The green LED D3 illuminates when VDD is supplied. VDD must be supplied for normal operation of the TMP113EVM as VDD is used for device power and communication line pullup voltages. VDD can be supplied via the on-board sub-regulator U1 or external power. See Section 2.5 for more details.

The yellow LED D6 illuminates when the ALERT pin is low. The default software configuration of the ALERT pin is active-low, and the LED illuminates when ALERT becomes active or "trips".

The red LED D4 is the MSP430F5528 status LED. Table 2-2 shows how the different modes of operation are displayed by the LED status.
