TAP Controller State Machine Figure 11.2A
Test-Logic-Reset
Upon power-up of the DS3134, the TAP controller will be in the Test-Logic-Reset state. The Instruction
register will contain the IDCODE instruction. All system logic on the DS3134 will operate normally.
Run-Test-Idle
Run-Test-Idle is used between scan operations or during specific tests. The Instruction register and Test
register will remain idle.
Select-DR-Scan
All test registers retain their previous state. With JTMS low, a rising edge of JTCLK moves the
controller into the Capture-DR state and will initiate a scan sequence. JTMS high moves the controller to
the Select-IR-SCAN state.
