Figure 33. TAP States
When the correct logic sequence is applied to the TMS and TCK inputs, the TAP will exit the Test-Logic-Reset state
and move to the desired state. The next state after Test-Logic-Reset is Run-Test/Idle. Until a data or instruction shift
is performed, no action will occur in Run-Test/Idle (steady state = idle). After Run-Test/Idle, either a data or instruc-
tion shift is performed. The states of the Data and Instruction Register blocks are identical to each other differing
only in their entry points. When either block is entered, the rst action is a capture operation. For the Data Regis-
ters, the Capture-DR state is very simple: it captures (parallel loads) data onto the selected serial data path (previ-
ously chosen with the appropriate instruction). For the Instruction Register, the Capture-IR state will always load
the IDCODE instruction. It will always enable the ID Register for readout if no other instruction is loaded prior to a
Shift-DR operation. This, in conjunction with mandated bit codes, allows a “blind” interrogation of any device in a
compliant IEEE 1149.1 serial chain. From the Capture state, the TAP transitions to either the Shift or Exit1 state.
Normally the Shift state follows the Capture state so that test data or status information can be shifted out or new
data shifted in. Following the Shift state, the TAP either returns to the Run-Test/Idle state via the Exit1 and Update
states or enters the Pause state via Exit1. The Pause state is used to temporarily suspend the shifting of data
through either the Data or Instruction Register while an external operation is performed. From the Pause state,
shifting can resume by reentering the Shift state via the Exit2 state or be terminated by entering the Run-Test/Idle
state via the Exit2 and Update states. If the proper instruction is shifted in during a Shift-IR operation, the next entry
into Run-Test/Idle initiates the test mode (steady state = test). This is when the device is actually programmed,
erased or veried. All other instructions are executed in the Update state.
Test Instructions
Like data registers, the IEEE 1149.1 standard also mandates the inclusion of certain instructions. It outlines the
function of three required and six optional instructions. Any additional instructions are left exclusively for the manu-
facturer to determine. The instruction word length is not mandated other than to be a minimum of two bits, with only
the BYPASS and EXTEST instruction code patterns being specically called out (all ones and all zeroes respec-
tively). The ispClock5300S contains the required minimum instruction set as well as one from the optional instruc-
tion set. In addition, there are several proprietary instructions that allow the device to be congured and veried.
