addressed by EA are loaded into the low-order 8 bits of rD. Bits
8–15 of the word in memory addressed by EA are loaded into the
subsequent low-order 8 bits of rD. Bits 16–23 of the word in
memory addressed by EA are loaded into the subsequent
low-order eight bits of rD. Bits 24–31 of the word in memory
addressed by EA are loaded into the subsequent low-order 8 bits
of rD. The MPC823 may run the lwbrx instructions with greater
latency than other types of load instructions.
Other registers altered:
