ETM resources

14-8
Because the ETM does not generate data trace information, the lower bandwidth
reduces the requirement for complex triggering capabilities. This means that the ETM
does not include the following:
• internal comparators
• counters
• sequencers.
Table 14-7 lists the Cortex-M3 resources.
