†
The data logging mode that uses the word counter allows this combination, but not the data logging mode that
uses the end address (see section 7.8, Data Logging).
7-30
You can use analysis breakpoints, watchpoints, and a benchmark/event
counter through the debugger, and you can use data logging through applica-
tion code. Table 7−6 lists the analysis resources, and Figure 7−10 shows
which resources are available to be used at the same time.
When the application owns analysis resources, they will be cleared (made un-
owned and set to the completed state) by a reset. When the debugger owns
the resources, they are not cleared by reset but by the JTAG test-logic reset.
This ensures that when you are using the debugger, the resources can be
used even while the target system undergoes a reset.
Resource Purpose

BD Break on contents of program data, memory read data, or memory
write data in addition to an address bus
