2.8 External Interrupts
Two on-board push-button switches are provided for external interrupt generation, as
shown in
Figure 2-9
. 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.
