Using EXTI only for software interrupt?

Question asked by hello188 on Jan 15, 2014
Hi. Is it possible to setup EXTI_LineX so that it is only triggered by EXTI_GenerateSWInterrupt(EXTI_Linex) library function? and NOT triggered by any hardware condition?

It seems that even if I omit the code for linking GPIO_PORT to EXTI_Line, it automatically links EXTI_Line to GPIOA. 
GPIOA happen to have SPI clock, which I think is triggering EXTI interrupt on every falling edge.

Anyone have idea??

Thank you
