(3)Settings when the End Address Is Greater than the Final Ad-
dress in the Data Carrier
(End address > 07FFH)
The Data Carrier memory area is from addresses 0000H to 07FFH.
Therefore, the addresses up to 07FFH will be write-protected.

dress
(Start address > End address)
The area between 0006H and the end address and the area
between the start address and 07FFH will be write-protected.

Canceling Write Protection
To cancel write protection, set the most significant bit of address 0002H to 0. The write protection will be
cancelled, and the start and end addresses that are set in 0002H to 0005H will be ignored.
