standard pins, TRSTB, TCK, TMS, TDI and TDO used to control the TAP  
controller and the boundary scan registers. The TRSTB input is the active-low  
reset signal used to reset the TAP controller. TCK is the test clock used to  
sample data on input, TDI and to output data on output, TDO. The TMS input is  
used to direct the TAP controller through its states. The basic boundary scan  
architecture is shown below.

The boundary scan architecture consists of a TAP controller, an instruction  
register with instruction decode, a bypass register, a device identification register  
and a boundary scan register. The TAP controller interprets the TMS input and  
generates control signals to load the instruction and data registers. The  
instruction register with instruction decode block is used to select the test to be  
executed and/or the register to be accessed. The bypass register offers a single-
