The ERRPIDR3 characteristics are:
Provides discovery information about the component.
For more information, see 'About the Peripheral identification scheme'.
Implementation of this register is OPTIONAL.
ERRPIDR3 is a 32-bit register.
The ERRPIDR3 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 |
RES0 | REVAND | CMOD |
Reserved, RES0.
IMPLEMENTATION DEFINED.
Component minor revision. ERRPIDR2.REVISION and ERRPIDR3.REVAND together form the revision number of the component, with ERRPIDR2.REVISION being the most significant part and ERRPIDR3.REVAND the least significant part. When a component is changed, ERRPIDR2.REVISION or ERRPIDR3.REVAND must be increased to ensure that software can differentiate the different revisions of the component. If ERRPIDR2.REVISION is increased then ERRPIDR3.REVAND should be set to 0b0000.
IMPLEMENTATION DEFINED.
Customer Modified.
Indicates the component has been modified.
A value of 0b0000 means the component is not modified from the original design.
Any other value means the component has been modified in an IMPLEMENTATION DEFINED way.
For any two components with the same Unique Component Identifier:
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 | REVISION | CMOD |
Reserved, RES0.
IMPLEMENTATION DEFINED.
Component revision. When a component is changed, ERRPIDR3.REVISION must be increased to ensure that software can differentiate the different revisions of the component.
IMPLEMENTATION DEFINED.
Customer Modified.
Indicates the component has been modified.
A value of 0b0000 means the component is not modified from the original design.
Any other value means the component has been modified in an IMPLEMENTATION DEFINED way.
For any two components with the same Unique Component Identifier:
Component | Offset |
---|---|
RAS | 0xFEC |
Accesses on this interface are RO.
