6.5.1 Comparison of RAM, ROM, and IC Memory Card Operation
With the FP2SH, the user can select “RAM operation”, “ROM operation”, or “IC memory
card operation” as the method by which programs are to be executed.
RAM operation
Programs written to the RAM in the CPU unit are executed.
ROM operation
With the FP2 − C2L or FP2 − C2, programs written to the ROM in the expansion memory
unit are sent once to the RAM and executed. With the FP2 − C2P or FP2 − C3P, programs
written to the internal FROM are sent once to the RAM and executed.
IC memory card operation (FP2 − C2P and FP2 − C3P are supported):
Programs written to the IC memory card are sent to the RAM and executed.
Item RAM operation
(SW2: off, SW4: —)
ROM operation
(SW2: on, SW4: off)
IC memory card operation
(SW2: on, SW4: on)
Items re-
quired for
operation
None in particular, because the
RAM provided as standard in
the CPU is used.
With the FP2 − C2L and FP2 − C2,
an optional memory unit and
ROM
The FP2
− C2P and FP2 − C3P
are built into the FROM.
FP2 − C2P or FP2 − C3P and IC
memory card with the program
written to it.
Processing
in the CPU
Program in the RAM is executed
when the RUN mode is ac-
cessed.
When the power supply is
turned on, the program in the
ROM is sent to the RAM, and
the program in the RAM is exe-
cuted.
When the power supply is
turned on, the program in the IC
memory card is sent to the
RAM, and the program in the
RAM is executed.

Maintenance Backup battery needs to be re-
placed.
If the program is in the operation
memory and does not use the
hold − type memory, operation is
possible without a battery.
If the program is in the operation
memory and does not use the
hold − type memory, operation is
possible without a battery.
With AIC52000, periodic charg-
ing or replacement is necessary.
Charging is done by inserting it
in the CPU.
With AFP2209, the replacement
of memory backup battery is
necessary.
