JTAG INSTRUCTION REGISTER
when the TAP controller is in the Shift-IR state. The instruction is decoded to
perform the following:
16 different possible instructions. Instructions are decoded as follows.
a complete description refer to the IEEE Standard Test Access Port Specification
(IEEE Std. 1149.1-1990).
EXTEST
test mode and selects the boundary-scan register to be connected between TDI
and TDO. During this instruction, the boundary-scan register is accessed to
drive test data off-chip via the boundary outputs and receive test data off-chip
via the boundary inputs. As such, the EXTEST instruction is the workhorse of
IEEE. Std 1149.1, providing for probe-less testing of solder-joint opens/shorts
and of logic cluster function.
IDCODE
and selects the optional device identification register to be connected between
TDI and TDO. The device identification register is a 32-bit shift register
containing information regarding the IC manufacturer, device type, and version
code. Accessing the device identification register does not interfere with the
operation of the IC. Also, access to the device identification register should be
immediately available, via a TAP data-scan operation, after power-up of the
IC or after the TAP has been reset using the optional TRST pin or by otherwise
moving to the Test-Logic-Reset state.
SAMPLE/PRELOAD
normal functional mode and selects the boundary-scan register to be connected
between TDI and TDO. During this instruction, the boundary-scan register can
be accessed via a date scan operation, to take a sample of the functional data
entering and leaving the IC. This instruction is also used to preload test data
into the boundary-scan register before loading an EXTEST instruction.
Value
The required EXTEST instruction places the IC into an external boundary-
