INTERRUPT SYSTEM
The ADuC816 provides a total of twelve interrupt sources with two priority levels. The control and configuration of the interrupt
system is carried out through three Interrupt-related SFRs.
IE:
Interrupt Enable Register.
IP:
Interrupt Priority Register.
IEIP2:
Secondary Interrupt Priority-Interrupt Register.
IE:
Interrupt Enable Register
