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 CLRC663 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 CLRC663: 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. 13 BC_1 - Control 12 BC_8 IF0 Bidir 11 BC_1 - Control 10 BC_8 IF1 Bidir 9 BC_1 - Control 8BC_8 IF2 Bidir 7 BC_1 IF2 Output2 6BC_4 IF3 Bidir 5 BC_1 - Control 4 BC_8 IRQ Bidir 3 BC_1 - Control 2 BC_8 SIGIN Bidir 1 BC_1 - Control 0 BC_8 SIGOUT Bidir Table 26.
