THE INSTRUCTION REGISTER
TheInstructionregisterallowsaninstructiontobeshiftedinseriallyintothe
processor at the rising edge of TCLK.
The Instruction is used to select the test to be performed, or the test data
registertobeaccessed,orboth. Theinstructionshiftedintotheregisterislatched
at the completion of the shifting process when the TAP controller is at Update-
IRstate.
The instruction register must contain 4 bit instruction register-based cells
whichcanholdinstructiondata. Thesemandatorycellsarelocatednearestthe
serial outputs they are the least significant bits.
TEST DATA REGISTER
The Test Data register contains three test data registers: the Bypass, the
Boundary Scan register and Device ID register.
These registers are connected in parallel between a common serial input
and a common serial data output.
The following sections provide a brief description of each element. For a
completedescription,refertotheIEEEStandardTestAccessPortSpecification
(IEEE Std. 1149.1-1990).
TEST BYPASS REGISTER
The register is used to allow test data to flow through the device from TDI
toTDO. Itcontainsasinglestageshiftregisterforaminimumlengthinserialpath.
When the bypass register is selected by an instruction, the shift register stage
is set to a logic zero on the rising edge of TCLK when the TAP controller is in
the Capture-DR state.
The operation of the bypass register should not have any effect on the
operation of the device in response to the BYPASS instruction.
THE BOUNDARY-SCAN REGISTER
The Boundary Scan Register allows serial data TDI be loaded in to or read
out of the processor input/output ports. The Boundary Scan Register is a part
of the IEEE 1149.1-1990 Standard JTAG Implementation.
THE DEVICE IDENTIFICATION REGISTER
The Device Identification Register is a Read Only 32-bit register used to
specify the manufacturer, part number and version of the processor to be
determined through the TAP in response to the IDCODE instruction.
IDT JEDEC ID number is 0xB3. This translates to 0x33 when the parity
is dropped in the 11-bit Manufacturer ID field.
For the IDT72V3640/72V3650/72V3660/72V3670/72V3680/72V3690,
the Part Number field contains the following values:

JTAG INSTRUCTION REGISTER
TheInstructionregisterallowsinstructiontobeseriallyinputintothedevice
when the TAP controller is in the Shift-IR state. The instruction is decoded to
perform the following:
Select test data registers that may operate while the instruction is
current. The other test data registers should not interfere with chip
operation and the selected data register.

TDI and TDO during data register scanning.
The Instruction Register is a 4 bit field (i.e.IR3, IR2, IR1, IR0) to decode 16
different possible instructions. Instructions are decoded as follows.

The following sections provide a brief description of each instruction. For
acompletedescriptionrefertotheIEEEStandardTestAccessPortSpecification
(IEEE Std. 1149.1-1990).
EXTEST
The mandatory EXTEST instruction is provided for external circuity and
board level interconnection check.
IDCODE
This instruction is provided to select Device Identification Register to read
out manufacture’s identity, part number and version number.
SAMPLE/PRELOAD
The mandatory SAMPLE/PRELOAD instruction allows data values to be
loadedontothelatchedparalleloutputsoftheboundary-scanshiftregisterprior
to selection of the boundary-scan test instruction. The SAMPLE instruction
allowsasnapshotofdataflowingfromthesystempinstotheon-chiplogicorvice

HIGH-Z

state.
BYPASS
The Bypass instruction contains a single shift-register stage and is set to
provide a minimum-length serial path between the TDI and the TDO pins of the
device when no test operation of the device is required.
