I'm a bit confused about Figure 22 in the ADT7310 datasheet (rev A), as far as the INT pin behavior in interrupt mode is concerned. According to the "Interrupt Mode" text on the same page (p. 21):
Once the INT pin is reset, it goes active again only when the temperature is greater than the temperature stored in the T_HIGH setpoint register or less than the temperature stored in the T_LOW setpoint register.
Consider the annotated Figure 22 below, where I've highlighted the behavior in interrupt mode with polarity set to active low. If that's the case, shouldn't the INT pin be asserted (go low) the next time the temperature exceeds T_high, at the indicated point in the figure?
While we're at it, I don't see why it gets asserted (in the figure) when the temperature drops below (T_high - T_hyst). I didn't want to clutter up the figure too much, though.
Is this figure correct? Thanks in advance for any clarification you can provide.
