DebugTable 12-44 Peripheral Identification Registers (continued)Offset Register number Function0xFE4 1017 Peripheral Identification Register 10xFE8 1018 Peripheral Identification Register 20xFEC 1019 Peripheral Identification Register 3Field Size FunctionTable 12-45 shows fields that are in the Peripheral Identification Registers.Table 12-45 Fields in the Peripheral Identification Registers4KB Count 4 bits Indicates the Log 2 of the number of 4KB blocks that the processor occupies. The debugregisters occupy a single 4KB block, therefore this field is always 0x0.JEP106 4+7 bits Identifies the designer of the processor. This field consists of a 4-bit continuation code and a7-bit identity code. Because the processor is designed by ARM, the continuation code is 0x4and the identity code is 0x3B.Partnumber12 bits Indicates the part number of the processor. The part number for the processor is 0xC08.Revision 4 bits Indicates the major and minor revision of the product. The major revision containsfunctionality changes and the minor revision contains bug fixes for the product. The revisionnumber starts at 0x0 and increments by 1 at both major and minor revisions. The processorrevision number is 0x5.RevAnd 4 bits Indicates the manufacturer revision number. This number starts at 0x0 and increments by theintegrated circuit manufacturer on metal fixes. For the processor, the initial value is 0x0 but canbe changed by the manufacturer.Customermodified4 bits For the processor, this value is 0x0.Table 12-46 shows how the bit values correspond with the Peripheral ID Register 0functions.Bits Field Function[31:8] - RAZ.Table 12-46 Peripheral ID Register 0 bit functions[7:0] - Indicates bits [7:0] of the part number for the processor. This value is 0x08.ARM DDI 0344E Copyright © 2006-2008 ARM Limited. All rights reserved. 12-67
