Hi,
I am desiging a board with the MC9S12DT256 MCU on it. I have a requirement of assigning two external interrupts from two external communication chips to the interrupt inputs of the MCU.
 
I have decided on using PJ0 and PJ1 (Port J) of MCU as edge triggered interrupt inputs for these external interrupts.
 
I do not want to use XIRQ or IRQ.
 
Please tell me if I can use PJ0 and PJ1 as external interrupt inputs.
 
Regards
Swaroop
