Product data sheet
13.1.2 Device identification codes
A device identification register is specified in “IEEE Std. 1149.1b-1994”. It is a 32-bit
register which contains fields for the specification of the IC manufacturer, the IC part
number and the IC version number. Its biggest advantage is the possibility to check for the
correct ICs mounted after production and to determine the version number of the ICs
during field service.
When the IDCODE instruction is loaded into the BST instruction register, the identification
register will be connected between pins TDI and TDO of the IC. The identification register
will load a component specific code during the CAPTURE_DATA_REGISTER state of the
TAP controller, this code can subsequently be shifted out. At board level this code can be
used to verify component manufacturer, type and version number. The device
identification register contains 32 bits, numbered 31 to 0, where bit 31 is the most
significant bit (nearest to TDI) and bit 0 is the least significant bit (nearest to TDO);
