ETM register summary

This section summarizes the ETM trace unit registers.

All ETM trace unit registers are 32-bit wide. The description of each register includes its offset from a base address. The base address is defined by the system integrator when placing the ETM trace unit in the Debug-APB memory map.

The following table lists all of the ETM trace unit registers.
