registers to be loaded with data.
n consecutive bytes starting at EA are loaded into GPRs rD
through rD + nr – 1. Bytes are loaded left to right in each register.
The sequence of registers wraps around to r0 if required. If the
4 bytes of register rD + nr – 1 are only partially filled, the unfilled
low-order byte(s) of that register are cleared. If rA is in the range
of registers specified to be loaded, including the case in which rA
= 0, the instruction form is invalid. Under certain conditions (for
example, segment boundary crossing) the data alignment
exception handler may be invoked.
