using PicoBlaze Vikram amp Chethan Advisor Prof Gandhi Puvvada Introduction An interrupt is a signal to the processor from hardware or software indicating an event that needs immediate attention. 256 interrupt disable interrupt enable 3520 How can I be sure that general interrupts will not be enabled too early Example function1 DINT GIE flag clear will disable general interrupts function2 A call to function2 EINT The final GIE flag set (Introduction to 8259) .
