EXTI on PC3 rising edge only : pull-down ?

Hi all,

One question about EXTI : I have to trigger an external interrupt on pin PC3 of my STM32F405RG.

So I have to configure EXTI3 for rising edge, but is it a good practice to enable pull down to avoid false triggering, instead of nopull ?

Tx in advance
