The ERRDEVARCH characteristics are:
Provides discovery information for the component.
ERRDEVARCH is implemented only as part of a memory-mapped group of error records.
ERRDEVARCH is a 32-bit register.
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 |
ARCHITECT | PRESENT | REVISION | ARCHVER | ARCHPART |
Defines the architect of the component. For RAS, this is Arm Limited.
Bits [31:28] are the JEP106 continuation code, 0b0100.
Bits [27:21] are the JEP106 identification code, 0b0111011.
Reads as 0b01000111011.
Access to this field is RO.
DEVARCH present. Indicates that the ERRDEVARCH register is present.
Reads as 0b1.
Access to this field is RO.
Revision. Defines the architecture revision of the component.
The value of this field is an IMPLEMENTATION DEFINED choice of:
