• RA is in the range of registers to be loaded
•RA=RT=0
Programming Note
This instruction can be restarted, meaning that it could be interrupted after having already updated some of
the target registers, and then re-executed from the beginning (after returning from the interrupt), in which
case the registers which had already been loaded prior to the interrupt will be loaded a second time. Note that
if RA is in the range of registers to be loaded (an invalid form; see above) and is also one of the registers
which is loaded prior to the interrupt, then when the instruction is restarted the re-calculated EA will be incor-
rect, since RA will no longer contain the original base address. Hence the definition of this as an invalid form
which software must avoid.
