1. When set high, INTB will be set to high impedance.  
2. Enable cell OEB_pinname, tristates pin pinname when set high.  
3. OEB_INTB is the first bit of the boundary scan chain.  
4. Cells ‘Logic one’ are Input Observation cells whose input pad is bonded to VDD internally.  
11.2.1 Boundary Scan Cells  
In the following diagrams, CLOCK-DR is equal to TCK when the current controller state is  
SHIFT-DR or CAPTURE-DR, and unchanging otherwise. The multiplexer in the center of the  
diagram selects one of four inputs, depending on the status of select lines G1 and G2. The ID  
Code bit is as listed in the Boundary Scan Register, Table 14.
