NOTES:
1. DOEB is the active low output enable for D[7:0].
2. RDATOEB is the active low output enable for RSOP, RSX, RDAT[15:0],
and RPRTY.
3. RPAOEB is the active low output enable for RPA.
4. TPAOEB is the active low output enable for TPA.
5. When set high, INTB will be set to high impedance.
6. RX8KOEB is the active low output enable for RX8K.
7. RX8KOEB is the first bit of the boundary scan chain scanned in and out.
It is closest to TDO.

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 centre 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.
