8.6 Register Maps

The TMP43x contain multiple registers for holding configuration information, temperature measurement results, temperature comparator maximum, minimum, limits, and status information. These registers are described in Figure 19 and in Table 3 for the TMP431, and in Table 4 for the TMP432.
