5.13 Vector Processor Registers
The <REFERENCE>(XRV) internal processor registers are
listed in Table 5–9. See Chapter 4 for the complete list of
IPR registers. The console program allows you to access the
vector registers. Software accesses the vector registers with
MTPR/MFPR and MTVP/MFVP instructions.
