RM48L952: Using HET pins as GPIO

Part Number: RM48L952
Other Parts Discussed in Thread: TCAN4550

Hello,

I'm trying to set up an interrupt on a HET pin that is being used as a GPIO input (it's a TCAN4550 interrupt pin).  I understand how to set these up as inputs and outputs, but is it possible to set up an interrupt on pin level change just as one would for a GPIOA or B pin?  From browsing the manual it seems that the HET interrupts are specific to timer related functions and the GPIO interrupts are only usable for ports A and B.

Thanks,
Jason
