13.6 Register summary

This section summarizes the ETM registers.

For full descriptions of the ETM registers, see:
  • 10.10 External debug interface, for the IMPLEMENTATION DEFINED registers and the ARM® Embedded Trace Macrocell Architecture Specification, ETMv4, for the other registers.

Note

  • In the following table, access type is described as follows:
    RWRead and write.
    RORead only.
    WOWrite only.
All ETM registers are 32 bits wide. The following table lists all of the registers and their offsets from a base address. The base address is defined by the system integrator when placing the ETM in the Debug-APB memory map.
