Typical sequence
Scanning in JTAG instruction

0
Assuming Run-Test/Idle is the present state, a typical scenario for using the JTAG interface is:
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. The TMS 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 cir-
cuitry 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.
