#1: PI/O RAM backup area (512 KB) and user area (1 MB)
#2: The first SDRAM address range is the physical address range in SDRAM. The address range in
parentheses is the corresponding address range in NAND flash memory. The data copied from the NAND
flash memory to SDRAM is stored in the file
backup1.bur
, and the MRAM data is stored in the file
backup3.bur
.
SDRAM state during ROM load operation
When creating or comparing backup data, downloading the CPMS, or initializing the task environment, the
data in the areas of the NAND flash memory shown in Figure 8-158 is copied to SDRAM by performing a
ROM load operation. The data is then read from the SDRAM in a cold-started state.
When a ROM load operation takes place, the entire main memory is initialized. If you are using the S10
bus memory space shown in
3.1 Logical space
in the
S10VE Software Manual CPMS General Description
and Macro Specifications
(manual number SEE-3-201) as the user area, you can use the data
transmit/receive function of LADDER DIAGRAM SYSTEM/S10VE to back up and restore the user area
as needed.
