CT and INT Operation in One-Shot Mode
See Figure 15 for more information on one-shot CT pin
operation for T
limits is exceeded. Note that in interrupt mode, a read from
any register resets the INT and CT pins.
For the INT pin in the comparator mode, if the temperature
drops below the T

configuration register, Register Address 0x01) resets the INT pin.

Note that when using one-shot mode, ensure that the refresh
rate is appropriate to the application being used.
