ICODE 3 (TagTamper)

8.5.3.22 WRITE CONFIG

Command code = C1h

The WRITE_CONFIG command writes the 4-byte data to the requested block address of the configuration

memory.

Access to the configuration blocks depends on the status and definition of the related block within the

configuration memory (see Section 8.2.3 "Configuration memory").

If the configuration memory is password protected, write access is only possible after the valid authentication

with the SET PASSWORD command with the Configuration password.

If the requested configuration block is not write accessible due to the actual status, the ICODE 3 responds with

Error_flag set (Table 122).

If the Configuration memory is write-locked with the OTP_CFG_LOCK bit (see Table 29), ICODE 3 responds

with Error_flag set.

The timing of the command is write alike.

Option 1 (Option flag set) is supported.

Option 0 (Option flag not set) is supported.
