For More Information On This Product,
NOTE: mtspr is supervisor-level only if SPR[0] = 1.
Simplified mnemonics:
In the PowerPC OEA, the SPR field denotes a special-purpose
register, encoded as shown in the following table. The contents
of rS are placed into the designated special-purpose register.
For this instruction, SPRs TBL and TBU are treated as separate
32-bit registers; setting one leaves the other unaltered.
The value of SPR[0] = 1 if and only if writing the register is a
supervisor-level operation. Execution of this instruction
specifying a defined and supervisor-level register when
MSR[PR] = 1 results in a privileged instruction type program
exception.
If MSR[PR] = 1 then the only effect of executing an instruction
with an SPR number that is not shown in the following table and
has SPR[0] = 1 is to cause a privileged instruction type program
exception or an illegal instruction type program exception. For all
other cases, MSR[PR] = 0 or SPR[0] = 0, if the SPR field
contains any value that is not shown in the table, either an illegal
instruction type program exception occurs or the results are
boundedly undefined.
