ICODE 3 (TagTamper)

8.5.3.7 LOCK PAGE PROTECTION CONDITION

Command code = B7h

The LOCK PAGE PROTECTION CONDITION command locks the protection pointer address and the status

of the page protection conditions. The Read and Write passwords must be transmitted first with the SET

PASSWORD command.

The timing of the command is write alike.

Also, setting the OTP_PPC_LOCK bit to 1 with a WRITE CONFIG command to block 27 of the configuration

memory can lock the protection pointer address and the status of the page protection conditions. See Table 9

and Table 24.

Note: Lock the Page Protection condition at the end of the initialization of the IC (recommendation).
