ERRFHICR1, Fault Handling Interrupt Configuration Register 1

The ERRFHICR1 characteristics are:

Purpose

Fault Handling Interrupt configuration register.

Configuration

This register is present only when (the Fault Handling 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 ERRFHICR1 are RES0.

ERRFHICR1 is implemented only as part of a memory-mapped group of error records.

Attributes

ERRFHICR1 is a 32-bit register.

Field descriptions

When the Fault Handling 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 Fault Handling 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 ERRFHICR1

If the implementation does not use the recommended layout for the ERRIRQCR registers then accesses to ERRFHICR1 are IMPLEMENTATION DEFINED.

ERRFHICR1 can be accessed through the memory-mapped interfaces:

Component	Offset	Instance
RAS	0xE88	ERRFHICR1

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 ERRFHICR2.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.
