Independent of the initial state of the TAP Controller, the Test-Logic-Reset state can always be
entered by holding TMS high for 5 TCK clock periods. This sequence should always be applied
at the start of a JTAG session to bring the TAP Controller into a defined state before applying
JTAG commands. Applying a 0 on TMS for 1 TCK period brings the TAP Controller to the Run-
Test/Idle state, which is the starting point for JTAG operations.
Assuming Run-Test/Idle is the present state, a typical scenario for using the JTAG Interface
follows.
At the TMS input, apply the sequence 1, 1, 0, 0 at the rising edges of TCK to enter the Shift
Instruction Register (Shift-IR) state. While in this state, shift the 5 bits of the JTAG instructions
into the JTAG instruction register from the TDI input at the rising edge of TCK. During shifting,
the JTAG outputs status bits on TDO, refer to
input must be held low during input of the 4 LSBs in order to remain in the Shift-IR state. The
JTAG Instruction selects a particular Data Register as path between TDI and TDO and controls
the circuitry surrounding the selected Data Register.
Apply the TMS sequence 1, 1, 0 to re-enter the Run-Test/Idle state. The instruction is latched
onto the parallel output from the shift register path in the Update-IR state. The Exit-IR, Pause-IR,
and Exit2-IR states are only used for navigating the state machine.
At the TMS input, apply the sequence 1, 0, 0 at the rising edges of TCK to enter the Shift Data
Register (Shift-DR) state. While in this state, upload the selected Data Register (selected by the
present JTAG instruction in the JTAG Instruction Register) from the TDI input at the rising edge
of TCK. In order to remain in the Shift-DR state, the TMS input must be held low. While the Data
Register is shifted in from the TDI pin, the parallel inputs to the Data Register captured in the
Capture-DR state is shifted out on the TDO pin.
