Protection information
Write-protect data set in the ID Tag is returned.
Protect Data
The protect data item on each page is expressed by single-bit data. Protect data
items are arranged in decreasing numerical order beginning with those on page
30. There are protect data items on two zero-fixed pages after the protect data
item on page 1.
Three 32-bit data items are considered to be binary data, the hexadecimal con-
version of which is used as protect data.
The V700-D13P
jj
, however, uses the data items on page 1 through 14 only.
The data on any other page can be set or released, which has, however, nothing
to do with the operation of the V70-D13P
jj
.
