Table 50. TAP State Description
TAP Controller
The TAP controller is a 16-state synchronous state machine controlled by the TMS input and
clocked by TCK (see

State
In this state the test logic is disabled. The device is set to normal operation mode. While in
this state, the instruction register is set to the ICODE instruction.
The TAP controller stays in this state as long as TMS is Low. Used to perform tests.
The Boundary Scan Data Register (BSR) is loaded with input pin data.
Shifts the selected test data registers by one stage toward its serial output.
Data is latched into the parallel output of the BSR when selected.
Used to load the instruction register with a fixed instruction.
Shifts the instruction register by one stage.
Loads a new instruction into the instruction register.
Momentarily pauses shifting of data through the data/instruction registers.
Temporary states that can be used to terminate the scanning process.
