D7.2 PMPCSSR, Snapshot Program Counter Sample Register

The PMPCSSR is an alias for the PCSR register.

However, unlike the other view of PCSR, it is not sensitive to reads. That is, reads of PMPCSSR through the PMU snapshot view do not cause a new sample capture and do not change CIDSR, CID2SR, or VIDSR.

Bit field descriptions

The PMPCSSR is a 64-bit read-only register.
