MC20 Power Consumption

I am using MC20 what i have seen is that it take 20 mA of current when fully functional and when we bring down DTR to high state change in current is around 1 mA means current consumption reduces from 20 mA to 19 mA it is correct or is their something wrong i am doing ?
Please suggest any other setting because datasheet say that the current is reduce to around 1 mA when DTR gets high.

if we want to enter sleep mode , besides pull up DTR , pls send the below AT
