      Hi:

         When we use this chip, we encountered the following problems:

         1 How long did it take to switch the Swtiched Power(VTP<= 2.6V)?

         2 What circumstances the Oscillator Enable bit(OSEN-----register 01h bit 7)becomed 1?

         3 The battery has electricity, but the time is 2099 or 2050,why?The battery is  SL-840P(Manufacturer:Tadiran Batteries).
        Looking forward to your reply,thanks!
