PRCM Functional Description
3.5.5 PRCM Interrupts
Table 3-77 lists the interrupts from the PRCM module to the MPU and the IVA2.
Table 3-77. Interrupt Descriptions
Interrupt Name Mapping Description
PRCM_MPU_IRQ M_IRQ_11 To MPU interrupt controller (MPU INTC)
PRCM_IVA_IRQ IVA2_IRQ[12] To IVA2.2 wake-up controller (IVA2.2 WUGEN)
Table 3-78 and Table 3-79 summarize the event flags (in PRM_IRQSTATUS_MPU and
PRM_IRQSTATUS_IVA2 registers) and mask (in PRM_IRQENABLE_MPU and PRM_IRQENABLE_IVA2
registers) related to the events generating PRCM interrupts to the MPU and the IVA2.
