Figure 14-2. TAP Controller State Diagram
14.2 Instruction Register
The instruction register contains a shift register as well as a latched parallel output and is 3 bits in length. When
the TAP controller enters the Shift-IR state, the instruction shift register is connected between JTDI and JTDO.
While in the Shift-IR state, a rising edge on JTCLK with JTMS LOW will shift the data one stage towards the serial
output at JTDO. A rising edge on JTCLK in the Exit1-IR state or the Exit2-IR state with JTMS HIGH will move the
controller to the Update-IR state. The falling edge of that same JTCLK will latch the data in the instruction shift
register to the instruction parallel output. Instructions supported by the DS26521 and its respective operational
binary codes are shown in
