Parts and Functions
2.6 IC Memory Card (for FP2-C2P/FP2-C3P)
Example:
A 2MB card can be formatted as 1 MB, with 1 MB being used
as a "format field" and the remaining 1 MB being used as an
"expanded memory field".
The entire field can be used as a "format field" or as an "ex-
panded memory field", and the card used exclusively as a
memory card for saving programs or data memory.
If the FROM section is specified as the "expanded memory
field", the card can be used only for reading data.

Notes
•
Both the SRAM and FROM type can be divided into a "format
field" and an "expanded memory field" for use.

When using the card as a program memory, there are four
ways to read programs:
− Programs are read automatically when the power is turned
− Programs are read using the "ROM → RAM" operation of
− Programs are read using the "IC Card Service" of pro-
− Programs are read using the F14 (PGRD) instruction of the
