GICM_SETSPI_SR, Set Secure SPI Pending Register

The GICM_SETSPI_SR characteristics are:

Purpose

Adds the pending state to a valid SPI.

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

This register is present only when GICM_TYPER.SR == 1. Otherwise, direct accesses to GICM_SETSPI_SR are RES0.

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

GICM_SETSPI_SR is a 32-bit register.

RES0																			INTID

Reserved, RES0.

This field is an alias of GICD_SETSPI_SR.

Writes to this register have no effect if:

16-bit accesses to bits [15:0] of this register must be supported.

This interface is accessible as follows:

When GICD_CTLR.DS == 1, accesses to this register are WI.
When GICD_CTLR.DS == 0 and an access is Secure, accesses to this register are WO.
When GICD_CTLR.DS == 0 and an access is Non-secure, accesses to this register are WI.
When GICD_CTLR.DS == 0, FEAT_RME is implemented and an access is Root, accesses to this register are WO.
When GICD_CTLR.DS == 0, FEAT_RME is implemented and an access is Realm, accesses to this register are WI.
