BQ24450 interfacing with Microcontroller

Other Parts Discussed in Thread: BQ24450

Hello,

I am designing a smart battery charger with BQ24450 interfaced with a Microcontroller. I can connect STAT1 and STAT2 pins to monitor charging mode of the IC, right? Please guide me in schematics of the Fig 7 of the Evaluation board  how will I be connecting these pins to MCU? STAT1 is already pulled up by VDR here. Please suggest is it possible with this schematics, how should I?

Thanks.

    Hi,
    Did you solve the problem?
    I have the same problem, I did not understand how to connect the two pins (STAT1 and STAT2) to Arduino.
    I realized that without a battery on the two pins is a voltage greater than 5v, so I decided to insert two 5.1V zener with a 1K resistor and put it on digital arduino pins, but it does not work.
