INTERRUPT SYSTEM
The ADuC834 provides a total of 11 interrupt sources with two priority levels. The control and configuration of the interrupt system
is carried out through three interrupt-related SFRs. These are the IE (Interrupt Enable) Register, the IP (Interrupt Priority Register)
and the IEIP2 (Secondary Interrupt Enable/Priority SFR) Registers. Their bit definitions are given in the Tables XXXV – XXXVII.
