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.
There are no configuration notes.
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 |
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.
