5.2.2 Temperature ALERT and THERM Limits The first tab on the TMP451EVM software is Temperature Limits. In this tab you can read or set the ALERT and THERM limits for the TMP451. You can also set a temperature offset for the remote temperature sensor and enable a THERM hysteresis. -
Page 17: Configuration Register Tab
Figure 5-4. Temperature Limits Tab 5.2.3 Configuration Register Tab The TMP451EVM software contains a tab for the configuration register, consecutive alert register, and status register. Changing values in this register automatically writes them. In the Configuration register the bit MASK1 masks the ALERT pin when enabled. R/S stands for RUN/STOP, when enabled this sets the TMP451 to standby. -
