Profiling Control Register
The Profiling Control Register (PCTRLR) is used to enable (start) profiling and disable (stop)
profiling. It is also used to configure whether to count the number of executed instructions
or the number of executed clock cycles, as well as define the Profiling Buffer bin usage.
This register is a write-only register. Issuing a read request has no effect, and undefined
data is read. See the following figure and table.
The Bin Control value (B) can be calculated by the formula:
where:
-
L is the Profiling Low Register
-
H is the Profiling High Register
-
S is the parameter C_DEBUG_PROFILE_SIZE.
Profiling Low Address Register
The Profiling Low Address Register (PLAR) is used to define the low word address of the
profiled area. This register is a write-only register. Issuing a read request has no effect, and
undefined data is read. See the following figure and
Table 2-57.
