Table11-32 Fields in the Peripheral Identification Registers

Field Size Description

4KB Count 4 bits Indicates the Log2 of the number of 4KB blocks occupied by the debug device. The processor

debug registers occupy a single 4KB block, therefore this field is always

0x0

JEP106

Identity

Code

4+7 bits Identifies the designer of the processor. This field consists of a 4-bit continuation code and a

7-bit identity code. Because the processor is designed by ARM, the continuation code is

0x4

and the identity code is

0x3B

. For more information see JEP106M, Standard Manufacture’s

Identification Code.

Part number 12 bits Indicate s the part number of the processor. The part number for the processor is

0xC14

Revision 4 bits Indicates the major and minor revision of the product. The major revision contains

functionality changes and the minor revision contains bug fixes for the product. The revision

number starts at

0x0

and increments by 1 at both major and minor revisions. See Product

revision information on page1-24 for details of the value of this field.

RevAnd 4 bits Indicates the manufacturer revision number. This number starts at

0x0

and increments by the

integrated circuit manufacturer on metal fixes. For the Cortex-R4 processor, the initial value is

0x0

but this value can be changed by the manufacturer.

Customer

modified

4 bits Indicates an endorsed modification to the device. On this processor the value is always

0x0
