AM3359: RTC current draw

Part Number: AM3359


Hi,

We are using CR2032 battery for RTC back up and trying to calculate RTC battery shelf life for one of our board which uses Sitara processor AM3359BZCZA80 when it is not powered on or in deep sleep mode.

Can we able to know what is the current drawn by VDDS RTC pin D7 of this processor during deep sleep mode or no other power input is provided to processor except RTC section? This will help us to calculate RTC battery shelf life.
