Hello, i need to program a T89C51CC01 with Keil. I really don't know whether I should ask my question in this forum, but I just try. EX0 (external interrupt 0) gets executed. While the procedure is running I get another interrupt EX1 (external interrupt 1). But this interrupt doesn't get accepted. I think it is because of the EX0. How can I handle 2 Interrupts at the same time??? Till
