RTC Battery of ADSP-SC589 EZITE is not charged.

Dear ADI,

I have a question about ADSP-SC589 EZITE.

Below this is a RTC part of schematics for ADSP-SC589 EZLITE. 


I apply SuperCap(that spec is attached a file) to RTC battery(J1).

But SuperCap is not charged.(That device is powered on in 12 hours.)

So, I have a question.

For RTC supercap charing, Is that RTC circuit need to modified? Or need to setting register of ADSP-SC589?

Please, reply my question.


Thank you.

Best Regards,

Inho Jeon.
