BQ2004 -dT/t detection

Hi

I have some question about -dT/t detection on state diagram.

1. At the pending state( Vtemp> VLTF or Vtemp< VHTF) it is in pulse trickle charging state. Is that correct?

2.The temperature is sampled at the voltage at the TS pin every 34s.

   Each sampling is detected that states (Vtemp is compared with VLTF and VHTF.) as well.  Is that correct?

3.The fast charging is terminated when the temperature is exceed the temperature range. Then the state goes into the trickle charging state for keeping full charge.

   Is that correct?

Regards,
