Reset Value:
• PRIOR: Priority Level (Code Label AIC_PRIOR)
Program the priority level for all sources except source 0 (FIQ).
The priority level can be between 0 (lowest) and 7 (highest).
The priority level is not used for the FIQ, in the SMR0.
• SRCTYPE: Interrupt Source Type (Code Label AIC_SRCTYPE)
Program the input to be positive or negative edge-triggered or positive or negative level sensitive.
The active level or edge is not programmable for the internal sources.
