I am using an MC9S08AW32 processor and I will not be using the IRQ function. I need to know how to terminate the unused pin. The literature is a bit confusing in that it describes that an "optional" internal pull-up or pull-down resistor can be used. It says, "when this [IRQPE] bit is set, either an internal pull-up or an internal pull-down resistor is enabled depending on the state of the IRQEDG bit." Does that mean when IRQPE = 0 there is no internal resistor selected?
I just need to know whether to pull the pin low externally or not. I guess I could just do that, but I was not sure if an internal resistor was also active. Suggestions? Thanks.
Added p/n to subject.
