boundary scan contents and all input pins again capture the current external level
afterwards, and so on.
INTEST supports internal testing of the chip, i. e. the output pins capture the current level
on the corresponding internal line whereas all input pins are held on constant values (‘0’
or ‘1’). The resulting boundary scan vector is shifted to TDO. The next test vector is
serially loaded via TDI. Then all input pins are updated for the following test cycle.
SAMPLE/PRELOAD is a test mode which provides a snapshot of pin levels during
normal operation.
IDCODE: A 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’.
The ID code field is set to

Note: Since in test logic reset state the code ‘0011’ is automatically loaded into the
BYPASS: A bit entering TDI is shifted to TDO after one TCK clock cycle.
CLAMP allows the state of signals driven from component pins to be determined from
the boundary-scan register while the bypass register is selected as the serial path
between TDI and TDO. Signals driven from the MUNICH256 will not change while the
CLAMP instruction is selected.
HIGHZ places all of the system outputs in an inactive drive state.
