Boundary Scan Description Language (BSDL)

All of the boundary scan devices have a unique boundary structure which is necessary to

know for operating the device. Important components of this language are:

• available test bus signal

• compliance pins

• command register

• data register

• boundary scan structure (number and types of the cells, their function and the

connection to the pins.)

The MFRC630 is using the cell BC_8 for the IO-Lines. The I2C Pin is using a BC_4 cell.

For all pad enable lines the cell BC1 is used.

The manufacturer's identification is 02Bh.

• attribute IDCODEISTER of MFRC630: entity is "0001" and -- version

• "0011110010000010b" and -- part number (3C82h)

• "00000010101b" and -- manufacturer (02Bh)

• "1b";

-- mandatory

The user code data is coded as followed:

• product ID (3 bytes)

• version

These four bytes are stored as the first four bytes in the EEPROM.
