The RWPHI Register characteristics are:
In the ETR configuration, memory addresses are 40 bits wide. The RAM Write Pointer High Register sets the upper eight bits of the write pointer that is used together with the contents of the RWP Register, to write entries into the trace memory.
See the RAM Write Pointer Register.
Present in ETR configuration only.
