8.4.6.9 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 MFRC631 is using the cell BC_8 for the IO-Lines. The I
2
C 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 MFRC631: 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.
