Optional PM Attributes

Refer to Table 35-9 on this page and Table 35-10 on page 1049. All events in these attributes can also be sampled via the PortSamplesControl/PortSamplesResults mechanism. The PortSamplesControl.OptionMask attribute element indicates which, if any, of the optional events counters are implemented.

All of the implemented optional event counters contain zero after reset and clamp at a count of all ones. Writing zero clears the counter.

Table 35-11 on page 1050 through Table 35-19 on page 1065 provide a description of each of these optional attributes.
