ERRPIDR0, Peripheral Identification Register 0
The ERRPIDR0 characteristics are:
Provides discovery information about the component.
For more information, see 'About the Peripheral identification scheme'.
Implementation of this register is OPTIONAL.
ERRPIDR0 is a 32-bit register.
The ERRPIDR0 bit assignments are:
PART_0, bits [7:0]
Part number, bits [7:0].
The part number is selected by the designer of the component. The designer chooses whether to use a 12-bit or a 16-bit part number:
- If a 12-bit part number is used, it is stored in ERRPIDR1.PART_1 and ERRPIDR0.PART_0. There are 8 bits, ERRPIDR2.REVISION and ERRPIDR3.REVAND, available to define the revision of the component.
- If a 16-bit part number is used, it is stored in ERRPIDR2.PART_2, ERRPIDR1.PART_1 and ERRPIDR0.PART_0. There are 4 bits, ERRPIDR3.REVISION, available to define the revision of the component.
Accessing the ERRPIDR0
