Puts the system in RAM back-up state by
executing the POF instruction after execut-
ing the EPOF instruction.
However, the voltage drop detection circuit
is valid.
Note:
If the EPOF instruction is not executed before
executing this instruction, this instruction is
equivalent to the NOP instruction.
