IRQ_ACK (PMU_IOMODULE) Register

IRQ_ACK (PMU_IOMODULE) Register Description

Register NameIRQ_ACK
Relative Address0x000000003C
Absolute Address 0x00FFD4003C (PMU_IOMODULE)
Width32
TypemixedMixed types. See bit-field details.
Reset Value0x00000000
DescriptionInterrupt Acknowledge Register

This register is used as a command register for clearing individual interrupts in IRQ_STATUS and IRQ_PENDING registers. All bits set to 1 clear the corresponding bits in the IRQ_STATUS and IRQ_PENDING registers. The register is write-only
