When I put a function call in #int_ext I get an out of rom error. The function I'm calling reads the eeprom and reads the rtc clock. Any know what I'm doing wrong? I can do a printf function call.

If your application is not timing critical I would simply set a bit, in the interrupt service routine, that would enable the function to be called in the main body.

How much remaining space in ROM did you have if you don't call that particular function in the ISR?
