The Profiling Data Write Register (PDWR) writes a new value to the bin indicated by the Profiling Buffer Address Register and increments the Profiling Buffer Address Register. This register is a write-only register. Issuing a read request has no effect, and undefined data is read.
This register can be used to clear the Profiling Buffer before enabling profiling.
The four most significant bits in the Profiling Buffer bin are set to zero when writing the new value. See the following figure and table.
