Debug10.4.19 Claim Tag Clear RegisterThe DBGCLAIMCLR characteristics are:PurposeUsed by software to read the values of the CLAIM bits, and to clear thesebits to zero.Usage constraints Use in conjunction with the DBGCLAIMSET register. SeeDBGCLAIMSET bit assignments on page 10-29.ConfigurationsAvailable in all configurations.Attributes See the register summary in Table 10-1 on page 10-6.Figure 10-22 shows the DBGCLAIMCLR bit assignments.31 8 7 0ReservedCLAIMTable 10-21 shows the DBGCLAIMCLR bit assignments.Bits Name Function[31:8] - Reserved, RAZ/SBZP.Figure 10-22 DBGCLAIMCLR bit assignmentsTable 10-21 DBGCLAIMCLR bit assignments[7:0] CLAIM CLAIM bits. Writing a 1 to one of these bits clears the corresponding CLAIM bit to 0. A singlewrite operation can clear multiple bits to 0. Writing 0 to one of these bits has no effect.Reading the register returns the current values of these bits. The debug logic reset value of thesebits is 0.For more information about the CLAIM bits, see Claim Tag Set Register on page 10-29.10.4.20 Debug Device ID Register 1The DBGDEVID1 characteristics are:PurposeAdds to the information given by the DBGDIDR by describing otherfeatures of the debug implementation.Usage constraints There are no usage constraints.ConfigurationsThis register is required in all implementations.Attributes See the register summary in Table 10-1 on page 10-6.Figure 10-23 shows the DBGDEVID1 bit assignments.31 28 27 24 23 20 19 16 15 12 11 8 7 4 3 0UNKUNK UNK UNKUNK UNK UNKPCSROffsetFigure 10-23 DBGDEVID1 bit assignmentsARM DDI 0438I Copyright © 2011-2013 ARM.
