Yes, you are correct. The RC manual does indicate that digital inputs on the RC can also be outputs with some added code and no support from IFI. I was going for the simplest solution first. Per the RC...
"For advanced users, the first six digital I/O pins can be configured as hardware interrupts. While powerful, this feature can cause undesired operation if improperly used. Therefore Innovation First will not provide support for this feature. More details on using interrupts can be found by referring to the 18F8520 microcontroller datasheet and the MPLAB® C18 C Compiler User’s Guide. The Default Code has an interrupt handler written for these pins, but you must still configure and enable the interrupts to use them."
