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 located above.

When set high, INTB will be set to high impedance.
Enable cell OEB_pinname, tristates pin pinname when set high.
The first bit of the boundary scan chain is Logic one (register bit 291).
Cells titled ‘Logic one’ are Input Observation cells whose input pad has a pull-up and is unbonded.
Cells titled NC are Output or Bi-directional cells whose pad is unconnected to the device package.
The Output cell in register bit 264 is the active low output enable for the Bi-directional cell in register bit
263.
The Output cell in register bit 168 is the active low output enable for the Bi-directional cell in register bit
167.
The Output cell in register bit 86 is the active low output enable for the Bi-directional cell in register bit
85.
