This book is for the CoreSight Embedded Trace Macrocell™ for the Cortex-M4 and Cortex-M4F processors, the CoreSight ETM-M4 macrocell.
You implement the ETM-M4 macrocell with either the Cortex-M4 processor or the Cortex-M4F processor. In this manual, in general:
any reference to the processor applies to either the Cortex-M4 processor or the Cortex-M4F processor, as appropriate
any reference to the Cortex-M4 processor applies also to the Cortex-M4F processor, as appropriate.
The context makes it clear if information applies to only one of the processor options.
