Meaning
Stores the current restoration status.
•0: Before restoration
•1: Being executed
•2: Completed
•FF: Restoration error (In automatic restoration, "0:
Before restoration" is stored at the completion of
restoration.)
• This register stores the progress of restoration to the CPU
module in percentage (0 to 100%).
• "0" is stored at the start of restoration. In automatic
restoration, "0: Before restoration" is stored at the completion
of restoration.
• This register stores the maximum number of executions of
the writing to standard ROM instruction (SP.DEVST) per day.
• When the number of executions of the writing to standard
ROM instruction exceeds the number of times set by SD695,
"OPERATION ERROR" (error code: 4113) occurs.
• The setting range of this register is 1 to 32767. If "0" or a
value outside the range has been set, "OPERATION
ERROR" (error code: 4113) occurs at execution of the writing
to standard ROM instruction.
This register stores a free space value in a memory card in 32-
bit binary.
This register stores a free space value in a SD memory card if
the free space is insufficient for storing the backup data and
resulting in a backup error. (unit: byte) This register is cleared to
"0" when backup is completed.
This register stores backup data size in 32-bit binary.
