The RRPHI Register characteristics are:
In the ETR configuration, memory addresses are 40 bits wide. The RAM Read Pointer High Register sets the upper eight bits of the read pointer that is used together with the contents of the RRP Register to read entries from the trace memory over the APB interface.
For more information, see the RAM Read Pointer Register.
Present in ETR configuration only.
