107 / 140 page  MPC8640 and MPC8640D Integrated Host Processor Hardware Specifications, Rev. 1 Freescale Semiconductor 107 Signal Listings Note: 1. Multi-pin signals such as D1_MDQ[0:63] and D2_MDQ[0:63] have their physical package pin numbers listed in order corresponding to the signal names. 2. Stub Series Terminated Logic (SSTL-18 and SSTL-25) type pins. 3. If a DDR port is not used, it is possible to leave the related power supply (Dn_GVDD, Dn_MVREF) turned off at reset. Note that these power supplies can only be powered up again at reset for functionality to occur on the DDR port. 4. Low Voltage Differential Signaling (LVDS) type pins. 5. Low Voltage Transistor-Transistor Logic (LVTTL) type pins. 6. This pin is a reset configuration pin and appears again in the Reset Configuration Signals section of this table. See the Reset Configuration Signals section of this table for config name and connection details. 7. Recommend a weak pull-up resistor (1–10 k Ω) be placed from this pin to its power supply.
