SAMPLE/PRELOAD provides a snap-shot of the pin level during normal operation or is
used to preload (TDI) / shift out (TDO) the boundary scan with a test vector. Both
activities are transparent to the system functionality.
IDCODE Register
The 32-bit identification register is serially read out via TDO. It contains the version
number (4 bits), the device code (16 bits) and the manufacturer code (11 bits). The LSB
is fixed to "1".
Version
Note:
1. Update of IDCODE register: new version number is 4
2. In the state "test logic reset" the code "0100" is loaded into the instruction code
BYPASS, a bit entering TDI is shifted to TDO after one TCK clock cycle, e.g. to skip
testing of selected ICs on a printed circuit board.
