ERRCRICR0, Critical Error Interrupt Configuration Register 0

The ERRCRICR0 characteristics are:

Purpose

Critical Error Interrupt configuration register.

Configuration

This register is present only when (the Critical Error Interrupt is implemented or the implementation does not use the recommended layout for the ERRIRQCR registers) and interrupt configuration registers are implemented. Otherwise, direct accesses to ERRCRICR0 are RES0.

ERRCRICR0 is implemented only as part of a memory-mapped group of error records.

Attributes

ERRCRICR0 is a 64-bit register.

Field descriptions

When the Critical Error Interrupt is implemented, the implementation uses the recommended layout for the ERRIRQCR registers and the implementation uses simple interrupts:

63	62	61	60	59	58	57	56	55	54	53	52	51	50	49	48	47	46	45	44	43	42	41	40	39	38	37	36	35	34	33	32

When the implementation uses message-signaled interrupts, the Critical Error Interrupt is implemented and the implementation uses the recommended layout for the ERRIRQCR registers:

63	62	61	60	59	58	57	56	55	54	53	52	51	50	49	48	47	46	45	44	43	42	41	40	39	38	37	36	35	34	33	32

Bits [63:56]

ADDR, bits [55:2]

Message Signaled Interrupt address. (ERRCRICR0.ADDR << 2) is the address that the component writes to when signaling the Critical Error Interrupt. Bits [1:0] of the address are always zero.

The physical address size supported by the component is IMPLEMENTATION DEFINED. Unimplemented high-order physical address bits are RES0.

The reset behavior of this field is:

On an Error recovery reset, this field resets to an architecturally UNKNOWN value.

Bits [1:0]

Reserved, RES0.

When the implementation does not use the recommended layout for the ERRIRQCR registers:

63	62	61	60	59	58	57	56	55	54	53	52	51	50	49	48	47	46	45	44	43	42	41	40	39	38	37	36	35	34	33	32

Accessing ERRCRICR0

If the implementation does not use the recommended layout for the ERRIRQCR registers then accesses to ERRCRICR0 are IMPLEMENTATION DEFINED.

ERRCRICR0 can be accessed through the memory-mapped interfaces:

Component	Offset	Instance
RAS	0xEA0	ERRCRICR0

This interface is accessible as follows:

When the implementation uses message-signaled interrupts, (an access is Non-secure or an access is Realm), the implementation uses the recommended layout for the ERRIRQCR registers and ERRCRICR2.NSMSI configures the physical address space for message-signaled interrupts as Secure, accesses to this register are RO.
Otherwise, accesses to this register are RW.
