Bypasses the device during scan testing by providing a path
between TDI and TDO.
1 bit.
When the BYPASS instruction is the current instruction in the
instruction register, serial data is transferred from TDI to TDO in
the SHIFT-DR state with a delay of one TCK cycle. There is no
parallel output from the bypass register.
A logic 0 is loaded from the parallel input of the bypass register in
the CAPTURE-DR state.
Reads the 32-bit device identification code. No programmable
supplementary identification code is provided.
32 bits. The format of the register is as shown in Figure B-3.
When the IDCODE instruction is current, the ID register is
selected as the serial path between TDI and TDO. There is no
parallel output from the ID register.
