ADP5585

I was looking ADP5585 chip and it looks like it is going to fit in my requirements. It has 5*5 keypad configuration.

I need only 6 keys in my design. It does not matter if two is R and three is C or vice-verse.

How can I use ADP5585 if I want to use only 6 keys?

If you have better chip for my design/purpose please suggest me.

I will really appreciate your help and support.

Thank you,

PS
