2. To write-protect only 1 byte <start address = end address> Set the same ad-
dress as the start and end addresses.
3. If the end address exceeds the last address of the Data Carrier memory
(end address > 07FF):
Since the memory area of the Data Carrier is from 0000 through 07FF, ad-
dresses up to 07FF are write-protected.
4. If start address exceeds end address (start address > end address):
Addresses from 0006 through end address, and start address through 07FF
are write-protected.
