matrix button layout

Hi Guys,

    Greetings for the day.

    I am trying to design a 4*5 matrix button keyboard with CY8MBR3116.

    But I cannot find any details about the layout of capsense except a blur pic in the AN64846.

Is there any documents or example of the matrix button,can someone give me a hint ?

Thanks a lot!

Muchas Gracias!
