Original ITR processed whereas revised ITR still under processing

The processing of the revised ITR may take some time, and it will be based on the information provided in the revised return.

My question is that i have received the refund of my original ITR and revised ITR is still under processing  and also amount is a bit less. After 2 month, will they charge any interest or i need to pay the original minus revised ITR gap.

However, if your revised return results in an additional tax liability (i.e., you owe more taxes than initially reported), then interest may be calculated on the additional tax amount from the original due date of the return. The interest is typically calculated under Section 234B and Section 234C of the Income Tax Act.

NO my revised return is less than original one.I got refund of my original ITR and revised is still under processing. IN original ITR by mistake some field were being filled which i realize after filling. Only difference in number of refund of original and revised one.Taxes in original and revised will remain same just some allowance were by mistake i filed in original which i have corrected in Revised one and difference is 15k

Difference in refund i am talking about

If i got 25k of refund including interest from income tax side in original and in revise that be 5k then i need to pay 20k difference or more?I am talking about difference in refund
