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.
Present in ETR configuration only.
Figure 3.13 shows the RRPHI Register bit assignments.
Table 3.14 shows the RRPHI Register bit assignments.
