Will INTPn interrupts function properly when using INTPn pin?

Latest Updated:04/01/2006

Question:

I am using the INTPn pin as a port, and am using software to trigger INTPn interrupts (by setting an interrupt request flag).
There is no triggering by external input.
Will INTPn interrupts function properly when using this method?

Answer:

Unless there is edge detection of the INTPn pin, changes in the INTPn pin status cannot trigger interrupts.
There is no problem with software triggered interrupts in this case if the interrupt request flag is manipulated accordingly.
