Interrupt Flag Registers
The interrupt flags for the different interrupt sources are located in several special function registers. This
section describes the interrupt flags located in system registers or external interrupts belonging to system.
Other interrupt flags located in respective module registers are described in the specific module chapter. For
a complete listing of the interrupt flags and their assignment to SFRs, refer to
.
In case of software and hardware access to a flag bit at the same time, hardware will have higher priority.
