TAP Instruction Register Access
Accessing Data Registers
The test data registers in the Intel
the same way as the instruction register, with components (i.e., either the “capture” or
“update” functionality) removed from the basic structure as needed. Data registers are
accessed just as the instruction register is, only using the “select-DR-scan” branch of
the TAP finite state machine in
data register is selected for access by each TAP instruction. Note that the only
controller states in which data register contents actually change are Capture-DR, Shift-
DR, Update-DR and Run-Test/Idle. For each of the TAP instructions described below,
therefore, it is noted what operation (if any) occurs in the selected data register in each
of these four states.
Public TAP Instructions
Table 139, “Public TAP Instructions”
of the public TAP instructions. There are four 1149.1-defined instructions implemented
in Intel
data registers – the boundary scan, device ID, and bypass registers. The public
instructions can be executed with only the standard connection of the JTAG port pins.
This means the only clock required will be TCK. Full details of the operation of these
instructions can be found in the 1149.1 standard. The opcodes are 1149.1-compliant,
and are consistent with the Intel-standard encodings. A brief description of each
instruction follows. For more thorough descriptions refer to the IEEE 1149.1
specification.
