Master Interrupt Enable
Figure 65 illustrates a block diagram of the interrupt controller.
Figure 65. Interrupt Controller Block Diagram
The master interrupt enable bit (IRQE) in the Interrupt Control register globally enables
and disables interrupts.
Interrupts are globally enabled by any of the following actions:
•
•
•
Interrupts are globally disabled by any of the following actions:
•
•
•
•
Internal Interrupts
Port Interrupts
