The ERRDEVARCH characteristics are:
Provides discovery information for the component.
This register is present only when RAS is implemented. Otherwise, direct accesses to ERRDEVARCH are UNDEFINED.
ERRDEVARCH is a 32-bit register.
The ERRDEVARCH bit assignments are:
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 |
Architect.
Defines the architect of the component. Bits [31:28] are the JEP106 continuation code (JEP106 bank ID, minus 1) and bits [27:21] are the JEP106 ID code.
ARCHITECT | Meaning |
---|---|
0b01000111011 |
JEP106 continuation code 0x4, ID code 0x3B. Arm Limited. |
This field reads as 0x23B.
Other values are defined by the JEDEC JEP106 standard.
DEVARCH Present.
Defines that the DEVARCH register is present.
PRESENT | Meaning |
---|---|
0b0 |
Device Architecture information not present. |
0b1 |
Device Architecture information present. |
This bit is RAO.
Revision.
Defines the architecture revision of the component. The defined values of this field are:
REVISION | Meaning |
---|---|
0b0000 |
RAS System Architecture v1.0. |
0b0001 |
RAS System Architecture v1.1. As 0b0000 and also:
|
All other values are reserved.
Architecture Version.
Defines the architecture version of the component. The defined values of this field are:
ARCHVER | Meaning |
---|---|
0b0000 |
RAS System Architecture v1. |
This field reads as 0b0000.
All other values are reserved.
ARCHVER and ARCHPART are also defined as a single field, ARCHID, so that ARCHVER is ARCHID[15:12].
Architecture Part.
Defines the architecture of the component.
ARCHPART | Meaning |
---|---|
0xA00 |
RAS system architecture. |
This register reads as 0xA00.
ARCHVER and ARCHPART are also defined as a single field, ARCHID, so that ARCHPART is ARCHID[11:0].
Component | Offset | Instance |
---|---|---|
RAS | 0xFBC | ERRDEVARCH |
Access on this interface is RO.
