MC68HC908JB - Problems with Input and Output

Hi! I'm new at this forum and I hope I can get some help here.
I'm trying to use Port A for input and Output, configurable at realtime. It works if all the pins are outputs or inputs, but when I have both, the outputs don't work. I'm using the inputs as interrupts with KBI. The inputs work correctly but when I try to change an output pin it doesn't work.
Can anybody help me please?  thank you!
