5.5 Using a Memory Cartridge to Store Your Program
The CPUs support an optional memory cartridge that provides a portable
EEPROM storage for your program. The CPU stores the following elements on the
memory cartridge:
 User program
 Data stored in the permanent V memory area of the EEPROM
 CPU configuration
For more information about the memory cartridge, see Appendix A.
Copying to the Memory Cartridge
You can copy your program to the memory cartridge from the RAM only when the
CPU is powered on, the CPU is in STOP mode, and the memory cartridge is
installed.
!
Caution
Electrostatic discharge can damage the memory cartridge or the receptacle on the
CPU.
Make contact with a grounded conductive pad and/or wear a grounded wrist strap
when you handle the cartridge. Store the cartridge in a conductive container.
