ERRCRICR1, Critical Error Interrupt Configuration Register 1

The ERRCRICR1 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 ERRCRICR1 are RES0.

ERRCRICR1 is implemented only as part of a memory-mapped group of error records.

Attributes

ERRCRICR1 is a 32-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:

31	30	29	28	27	26	25	24	23	22	21	20	19	18	17	16	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0
RES0

Bits [31:0]

Reserved, RES0.

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

31	30	29	28	27	26	25	24	23	22	21	20	19	18	17	16	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0
DATA

DATA, bits [31:0]

Payload for the message signaled interrupt.

The reset behavior of this field is:

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

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

31	30	29	28	27	26	25	24	23	22	21	20	19	18	17	16	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0
IMPLEMENTATION DEFINED

IMPLEMENTATION DEFINED, bits [31:0]

IMPLEMENTATION DEFINED.

Accessing ERRCRICR1

If the implementation does not use the recommended layout for the ERRIRQCR registers then accesses to ERRCRICR1 are IMPLEMENTATION DEFINED.

This section shows the offset of ERRCRICR1 when FEAT_RASSA_4KB_GRP is implemented. If FEAT_RASSA_16KB_GRP or FEAT_RASSA_64KB_GRP is implemented, see 'RAS memory-mapped register views' for the offset of ERRCRICR1.

ERRCRICR1 can be accessed through the memory-mapped interfaces:

Component	Offset	Instance
RAS	0xEA8	ERRCRICR1

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.
