2.9 External Interrupts

Two on-board push-button switches are provided for external interrupt generation, as
shown in Figure 2-8. S2 allows the user to generate a hardware interrupt for signal line
IRQA. S3 allows the user to generate a hardware interrupt for signal line IRQB. These two
switches allow the user to generate interrupts for his user-specific programs.
