7.4 T _ CRIT _ A Output and T_CRIT flags
T _ CRIT _ A Output pulls low when the measured temperature exceeds the critical temperature
(T_CRIT) defined in 19h, and 20h for Remote, and Local T_CRIT set point, respectively. Once the
T _ CRIT _ A Output pulls high, it will not be reset until measured temperature is lower than (T_CRIT
－ TH), where TH is Temperature Hysteresis. The Status Register will not be reset until it is read and
the temperature conversion falls below the T_CRIT set point. Figure 7.4 shows this mechanism.
