GICD_CLRSPI_SR, Clear Secure SPI Pending Register

The GICD_CLRSPI_SR characteristics are:

Purpose

Removes the pending state from a valid SPI.

A write to this register changes the state of a pending SPI to inactive, and the state of an active and pending SPI to active.

Configuration

If GICD_TYPER.MBIS == 0, this register is reserved.

When GICD_CTLR.DS==1, this register is WI.

Attributes

GICD_CLRSPI_SR is a 32-bit register.

Field descriptions

The GICD_CLRSPI_SR bit assignments are:

0000000000000000000INTID

Bits [31:13]

Reserved, RES0.

INTID, bits [12:0]

The INTID of the SPI.

The function of this register depends on whether the targeted SPI is configured to be an edge-triggered or level-sensitive interrupt:
