ARM Cortex-A15 MPCore Processor Technical Reference Manual

Program Trace MacrocellTable 12-11 ETMCCER bit assignments (continued)Bits Name Function[22] Timestamping implemented Specifies that timestamping is implemented. For the Cortex-A15MPCore processor, this value is 1.[21:16] - RAZ.[15:13] Number of instrumentation resources Specifies the number of instrumentation resources. For theCortex-A15 MPCore processor, this value is 0.[12] - RAO.[11] All registers readable Indicates that all registers, except some Integration Test Registers,are readable. Registers with names that start with IT are theIntegration Test Registers, for example ITATBCTR1.[10:3] Extended External input bus size Specifies the size of the extended external input bus of 88.[2:0] Number of extended external input selectors Specifies the number of extended external input selectors:b010 Two selectors.12.7.9 Extended External Input Selection RegisterThe ETMEXTINSELR characteristics are:PurposeSelects the extended external inputs.Usage constraints There are no usage constraints.ConfigurationsAvailable in all PTM configurations.Attributes See the register summary in Table 12-4 on page 12-11.Figure 12-9 shows the ETMEXTINSELR bit assignments.31 15 148 7 60ReservedSecond extended external input selectorReservedFirst extended external input selectorTable 12-12 shows the ETMEXTINSELR bit assignments.Figure 12-9 ETMEXTINSELR bit assignmentsTable 12-12 ETMEXTINSELR bit assignmentsBits Name Function[31:15] - Reserved[14:8] Second extended external input selector Selects the second extended external input[7] - Reserved[6:0] First extended external input selector Selects the first extended external inputARM DDI 0438I Copyright © 2011-2013 ARM.
