2.3 Status LEDs and Subregulator

The switch S1 enables and disables the onboard 3.3-V regulator: U5. When the subregulator is enabled, the green LED D3 illuminates. The subregulator must be enabled for normal operation of TMP119EVM as the subregulator supplies power to the device and pullup voltage of the communication lines.

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.

D4 LED Status MSP430F5528 Mode of Operation
