2. The NC pads listed in this table are indeed no connects, but are represented in the boundary
3. In Boundary scan mode, differential input K and K are referred to each other and must be at
4. ZZ must remain at V
5. In boundary scan mode, ZQ must be driven to V
6. M1 and M2 must be driven to V
scan register by a “Place Holder”. Placeholder registers are internally connected to V
opposite logic levels for reliable operation.
