The GICD_STATUSR characteristics are:

Purpose

Provides software with a mechanism to detect:

If the GIC implementation supports two Security states this register is Banked to provide Secure and Non-secure copies.

GICD_STATUSR is a 32-bit register.

RES0																												WROD	RWOD	WRD	RRD

Reserved, RES0.

Write to an RO location.

WROD	Meaning
0b0	Normal operation.
0b1	A write to an RO location has been detected.

When a violation is detected, software must write 1 to this register to reset it.

Read of a WO location.

RWOD	Meaning
0b0	Normal operation.
0b1	A read of a WO location has been detected.

When a violation is detected, software must write 1 to this register to reset it.

Write to a reserved location.

WRD	Meaning
0b0	Normal operation.
0b1	A write to a reserved location has been detected.

When a violation is detected, software must write 1 to this register to reset it.

Read of a reserved location.

RRD	Meaning
0b0	Normal operation.
0b1	A read of a reserved location has been detected.

When a violation is detected, software must write 1 to this register to reset it.

This is an optional register. If the register is not implemented, the location is RAZ/WI.

GIC Distributor	Dist_base	0x0010	GICD_STATUSR (S)

This interface is accessible as follows:

When an access is Secure, accesses to this register are RW.
When FEAT_RME is implemented and an access is Root, accesses to this register are RW.
