Preliminary data sheet
6.25.2 Embedded trace buffer
The ARM core has a Debug Communication Channel function built-in. The debug
communication channel allows a program running on the target to communicate with the
host debugger or another separate host without stopping the program flow or entering the
debug state.
The Embedded Trace Module (ETM) is connected directly to the ARM core. It compresses
the trace information and exports it through a narrow trace port. An internal Embedded
Trace Buffer of 2 k
control. Data from the Embedded Trace Buffer is recovered by the debug software through
the JTAG port.
The trace contains information about when the ARM core switches between states.
Instruction trace (or PC trace) shows the flow of execution of the processor and provides a
list of all the instructions that were executed. Instruction trace is significantly compressed
by only broadcasting branch addresses as well as a set of status signals that indicate the
pipeline status on a cycle by cycle basis. For data accesses either data or address or both
can be traced.
