TEST_LOGIC/RESET
When the TAP controller is in the TEST_LOGIC/RESET state, the BST circuitry is
disabled, the device is in normal operation, and the instruction register is initialized
with IDCODE as the initial instruction. During device power up, the TAP controller
starts in this TEST_LOGIC/RESET state. In addition, the TAP controller may be forced to
the TEST_LOGIC/RESET state by holding TMS high for five TCK clock cycles. After the
TEST_LOGIC/RESET state, the TAP controller remains in this state as long as TMS
continues to be held high while TCK is clocked.

Figure 8–6. IEEE Std. 1149.1 Timing Waveforms
To start the IEEE Std. 1149.1 operation, select an instruction mode by advancing the
TAP controller to the shift instruction register (SHIFT_IR) state and shift in the
appropriate instruction code on the TDI pin.
