ICODE 3 (TagTamper)

8.5.3.14 LOCK EAS

Command code = A4h

The LOCK EAS command locks the current state of the EAS mode and the EAS ID. If the EAS mode is

password protected, the EAS password must be transmitted first with the SET PASSWORD command.

The timing of the command is write alike.

Option 0 (Option flag not set) is supported.

Option 1 (Option flag set) is supported.

Setting the OTP_EAS_LOCK bit to 1 with a WRITE CONFIG command to block 30 of the configuration memory

also locks the EAS mode and the EAS ID. See Table 9 and Table 30.
