4*4 keypad board - circuit connection

[nuarizzah]

Hi

I would like to ask about 4*4 keypad board; its circuit connection to PIC.
the keypad has 10 pins on the bottom. The problem is, i am not sure which pins are assigned as columns, and which pins are the rows? i already upload the figure just like my keypad.

thank you in advance.
