–
Grouping:
Other operation
Description: 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.

–
Grouping:
Other operation
Description: Puts the system in RAM back-up state by
executing the POF2 instruction after ex-
ecuting the EPOF instruction. Operations of
all functions are stopped.
Note:
If the EPOF instruction is not executed be-
fore executing this instruction, this
instruction is equivalent to the NOP instruc-
tion.
Operation:
RAM back-up
Operation:
RAM back-up
However, voltage drop detection circuit valid
