addressed by EA are loaded into the low-order eight bits of rD.
Bits 8–15 of the half word in memory addressed by EA are
loaded into the subsequent low-order eight bits of rD. The
remaining bits in rD are cleared.
The PowerPC architecture cautions programmers that some
implementations of the architecture may run the lhbrx
instructions with greater latency than other types of load
instructions.
