CHAPTER 2 DEPENDENCE FUNCTIONS
■ Trace Filter
To make effective use of the limited trace buffer capacity, in addition to the code fetch function, a trace filter
function is incorporated to provide a means of acquiring information about data accesses to a specific region.
The data trace filter function allows the following values to be specified for two regions:
- Address
- Address mask
- Access attribute (read/write)
Another function can be used so that sampling of redundant frames occupying two or more trace frames, such
as SLEEP and READY, can be reduced to sampling of one frame.
