DebugTable 10-2 DBGDIDR bit assignments (continued)Bits Name Function[12] SE_imp Security Extensions implemented bit.1 The processor implements Security Extensions.[11:8] - Reserved.[7:4] Variant This field indicates the variant number of the processor. This number is incremented on functionalchanges. The value matches bits[23:20] of the CP15 Main ID Register. See Main ID Register on page 4-27for more information.[3:0] Revision This field indicates the revision number of the processor. This number is incremented on bug fixes. Thevalue matches bits[3:0] of the CP15 Main ID Register. See Main ID Register on page 4-27 for moreinformation.10.4.2 Program Counter Sampling RegisterThe DBGPCSR characteristics are:PurposeEnables a debugger to sample the Program Counter (PC).Usage constraints ARM deprecates reading a PC sample through register 33 when theDBGPCSR is also implemented as register 40. DBGPCSR is not visible inthe CP14 interface.Configurations DBGPCSR is implemented as both debug register 33 and 40.Attributes See the register summary in Table 10-1 on page 10-6.Figure 10-3 shows the DBGPCSR bit assignments.31 1 0PCSTFigure 10-3 DBGPCSR bit assignmentsARM DDI 0438I Copyright © 2011-2013 ARM.

DebugTable 10-3 shows the DBGPCSR bit assignments.Table 10-3 DBGPCSR bit assignmentsBits Name Function[31:1] PCS Program Counter sample value. The sampled value of bits[31:1] of the PC. The sampled value iseither the virtual address of an instruction, or the virtual address of an instruction address plus anoffset that depends on the processor instruction set state.DBGDEVID1.PCSROffset indicates whether an offset is applied to the sampled addresses. Forthe Cortex-A15 MPCore processor, an offset is applied.[0] T This bit indicates whether the sampled address is an ARM instruction, or a Thumb or ThumbEEinstruction:0 If DBGPCSR[1] is 0, the sampled address is an ARM instruction.1 The sampled address is a Thumb or ThumbEE instruction.If T is 0 then DBGPCSR[1] is 0, ((DBGPCSR[31:2]
