The Profiling Data Read Register (PDRR) reads the bin value indicated by the Profiling Buffer Address Register and increments the Profiling Buffer Address Register. This register is a read-only register. Issuing a write request to the register does nothing. See the following figure and table.
When reading this register with MDM software access to debug registers, data is read with two consecutive accesses.
