Nonvolatility Memory (Word)/(DWord)
You can use the SRAM area as the non-volatile word memory area or the
non-volatile double-word memory area.
♦
Difference between Word and Double-word
The difference between word and double-word is whether the specified address
(= word) only is guaranteed or two words (double-word) from the address are
guaranteed when a power failure occurs. For more information, refer to “Data
Protection When a Power Failure Occurs” mentioned later.
* This is used when specifying $L or $LD indirectly by macro.
When specifying $L or $LD indirectly, specify the model as follows:
• $L/$LD0 to 65535: 00
MSB LSB
• $L/$LD65536 to 261983: 80
MSB LSB

Non-volatile Memory Setting
When setting the non-volatile memory using the screen editor V-SFT, if you are
using the word memory area, select [$L] in the [Internal Memory]. If you are
using double-word memory, select [$LD]. The available range is the address
space you select.
