23.8.1
The AIC is mapped at the address 0xFFFF F000. It has a total 4-Kbyte addressing space. This permits the vectoring fea-
ture, as the PC-relative load/store instructions of the ARM processor support only an ± 4-Kbyte offset.

Advanced Interrupt Controller (AIC) User Interface
1. The reset value of this register depends on the level of the external interrupt source. All other sources are cleared at reset,
2. PID2...PID31 bit fields refer to the identifiers as defined in the Peripheral Identifiers Section of the product datasheet.
