SL2S3003/SL2S3003TT

ICODE 3 (TagTamper)

To increment the counter by one with a WRITE SINGLE BLOCK command to block 75. If the password

protection to increment the counter is enabled, the read password needs to be transmitted to the label IC with

the SET PASSWORD command before (refer to Section 8.5.3.2 "SET PASSWORD").

The data for the WRITE SINGLE BLOCK command to increment the counter are defined in Table 133.

Note: The counter can be incremented only with the C0, C1 and C2 values defined in Table 134. If the write

password has been transmitted earlier with a SET PASSWORD command, the other values preset the counter

or lead to an error message.

Table 134. Increment counter by 1 data structure

To increment the counter by up to 255 (0xFF), issue a WRITE SINGLE BLOCK command to block 75. If the

password protection to increment the counter is enabled, the read password must be transmitted to the label IC

with the SET PASSWORD command first (refer to Section 8.5.3.2 "SET PASSWORD").

The data for the WRITE SINGLE BLOCK command to increment the counter are defined in Table 133.

Note: The counter can be incremented only with the C0, C1 and C2 values defined in Table 134. If the write

password has been transmitted earlier with a SET PASSWORD command, the other values preset the counter

or lead to an error message.
