Using the TMP451EVM Software
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. AL/TH stands for ALERT/THERM2. When this bit is enabled ALERT becomes a
second THERM. The TRange bit switches the TMP451 from its normal temperature range of 0°C–127°C
to its extended temperature range of –64°C–191°C. For the Consecutive Alert register the bit SMBus
enables a 30-ms timeout while bits 1–3 determine how many out-of-limit measurements are needed to
trigger an ALERT.
