The MSP430 monitors the light engine's thermistor to shutdown the EVM if excessive heat is measured on

the green LED. Passively cooled systems (no extra heat sinks or fans) have a thermal limit resulting in

LED currents under 633 mA. Actively cooled systems (extra heat sink and fan) have a thermal limit

resulting in LED currents under 1.5 A. Please see Table 2-1 for the corresponding LED current software

settings.
