7.7.1.2. Two-Times Interrupt Mode
Temperature exceeding T_O causes an interrupt and then temperature going below T_HYST will also
cause an interrupt if the previous interrupt has been reset by reading all the interrupt Status Register.
Once an interrupt event has occurred by exceeding T_O, then reset, if the temperature remains above
the T_HYST, the interrupt will not occur. (Figure 14-2)
7.7.1.3. One-Time Interrupt Mode
Temperature exceeding T_O causes an interrupt and then temperature going below T_HYST will not cause
an interrupt. Once an interrupt event has occurred by exceeding T_O, then going below T_HYST, an
interrupt will not occur again until the temperature exceeding T_O. (Figure 14-3)
