SAM9M10 [DATASHEET]
6355F–ATARM–12-Mar-13
 
28.9
Advanced  Interrupt  Controller  (AIC)  User  Interface
28.9.1
Base  Address
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 a ± 4-KByte offset. 
Notes:
1. The reset value of this register depends on the level of the external interrupt source. All other sources are cleared at reset, 
thus not pending.
2. PID2...PID31 bit fields refer to the identifiers as defined in the Peripheral Identifiers Section of the product datasheet. 
3. Values in the Version Register vary with the version of the IP block implementation.
