ERRPIDR0, Peripheral Identification Register 0

The ERRPIDR0 characteristics are:

Purpose

Provides discovery information about the component.

For more information, see 'About the Peripheral identification scheme'.

Configuration

Implementation of this register is OPTIONAL.

ERRPIDR0 is implemented only as part of a memory-mapped group of error records.

Attributes

ERRPIDR0 is a 32-bit register.

Field descriptions

The ERRPIDR0 bit assignments are:

313029282726252423222120191817161514131211109876543210
RES0PART_0

Bits [31:8]

Reserved, RES0.

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

ERRPIDR0 can be accessed through the memory-mapped interfaces:
