Hello, this is my first time that I ask something at ASS370 and it's : How can I make a assembler program that make this: - Disabled the key ALT PA1 and ALT PA2 ?????? I am making a reading routine and I don't want that others persons interrupts my program with ALT PA1 or ALT PA2. I hope your answer. Thanks in advance. Sergio Cruz.
