Variables That Can Be Monitored With Hwi - Texas Instruments TMS320 User Manual

Table 3-3. Variables that can be Monitored with HWI
To enable implicit HWI instrumentation:
1) Open the properties window for any HWI object and choose a register to
monitor in the monitor field.
You can monitor any variable shown in Table 3-3, or you can monitor
nothing. When you choose to monitor a variable, the configuration
automatically creates an STS object to store the statistics for the variable.

2) Set the operation parameter to the STS operation you want to perform on
this value.
You can perform one of the operations shown in Table 3-4 on the value
stored in the variable you select. For all these operations, the number of
times this hardware interrupt has been executed is stored in the count
field (see Figure 3-2). The max and total values are stored in the STS
object on the target. The average is computed on the host.
