Hi,

I am using GPIO pin # 20 for generating for interrupt on 8168.

i made requesting gpio and seting direction and converting gpio to irq. Now  I wanna(set) make this as FALLINGEDGE.

How do set irq fro FALLINGEDGE on 8168?

is any function i need use(pls mention the name of function) ?

I read the data Sheet  I need to set two GPIO register "GPIO_FALLINGDETECT,GPIO_IRQSTATUS_SET_0"  of  20 th bit in my Case. I can do this but if any function already doing means no need write one more function for this.

With Regards
