9.2.1.2Interrupt Controller IRQ Pending Register (ICIP) and FIQ Pending Register (ICFP)

The ICIP and the ICFP contain one flag per interrupt (32 total) that indicates an interrupt request has been made by a unit. Inside the interrupt service routine, the ICIP and ICFP are read to determine the interrupt source. In general, software then reads status registers within the interrupting device to determine how to service the interrupt.

Bits within the ICPR are read only, and represent the logical OR of status bits for a given interrupt within the source unit. Once an interrupt has been serviced, the handler clears the pending interrupt at the source by writing a one to the necessary status bit. Clearing the interrupt status bit at the source automatically clears the corresponding ICIP and ICFP flag provided there are no other interrupt status bits set within the source unit.

All interrupt source status bits are cleared by writing a one to them. Writing a zero to an interrupt status bit has no effect. The following table shows the bit locations corresponding to the 32 separate interrupt pending status flags in the ICIP. The next table shows the bit locations corresponding to the 32 separate interrupt pending status flags in the ICFP. This is a read-only register.
