• Stores the day and time when data is restored in 2-digit BCD code.

SD678

Restore time 
(Minute and 
second)

• Stores the minute and second when data is restored in 2-digit BCD 

code.

SD679

Restore time 
(Year and day of 
week)

• Stores the first 2 digits of year and day of week when data is restored in 

BCD code.

SD681

Program 
memory write

Write (transfer) 
status display 
(percentage)

Displays the status of writing (transferring) the program memory (flash

SD682

Program
memory write
count index

Write count index
up to present

• Stores the index value for the number of write operations to the program 

memory (flash ROM) up to the present in BIN 32-bit value.
When the index value exceeds 100 thousand times, "FLASH ROM 
ERROR" (error code: 1610) occurs. (The index value is calculated even 
when exceeding 100 thousand times.)

Note) The write count does not equal to the index value.(Since a flash 
ROM write life is prolonged by the system, 1 is added to the write count 
index when writing is performed twice or so.).

Write count index 
up to present

• Stores the index value for the number of write operations to the standard 

ROM (flash ROM) up to the present in BIN 32-bit value.
When the index value exceeds 100 thousand times, "FLASH ROM 
ERROR" (error code: 1610) occurs. (The index value is calculated even 
when exceeding 100 thousand times.)

Note) The write count does not equal to the index value. (Since a flash 
ROM write life is prolonged by the system, 1 is added to the write count 
index when the total write capacity after the previous count up reaches 
about 1M byte.)
