ICODE 3 (TagTamper)

8.5.3.21 READ CONFIG

Command code = C0h

The READ CONFIG command reads the requested number of blocks (n-1). The reading starts with the first

block defined by the 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 one of the requested configuration blocks is not accessible due to the actual status, the ICODE 3 responds

with Error_flag set (see Table 119).

Within one command execution, a READ_CONFIG command can read one or multiple blocks of the following

areas of the configuration memory:

• Block 0 to block 127

• Passwords cannot be read and are masked with 0x00 in the response

Block 41: CFG_PWD (Configuration password)

Block 42: READ_PWD (Read password

Block 43: WRITE_PWD (Write password)

Block 44: PRIVACY_PWD (Privacy password)

Block 45: DESTROY_PWD (Destroy password

Block 46: EASAFI_PWD (EAS/AFI password)

Block 47 (TT_OPEN_MSG) can only be read if it is not write-locked with the OTP_TT_OPEN_MSG_LOCK bit

(see Table 32) otherwise it is locked with all bytes 0x00.

Option 0 (Option flag not set) is supported.

Option 1 (Option flag set) is not supported.
