Notes:
1. See the DDR Control Driver registers in the MPC8641D reference manual for more information.
2. Only the following local bus signals have programmable drive strengths: LALE, LAD[0:31], LDP[0:3], LA[27:31], LCKE,
LCS[1:2], LWE[0:3], LGPL1, LGPL2, LGPL3, LGPL4, LGPL5, LCLK[0:2]. The other local bus signals have a fixed drive
strength of 45 ohms. See the POR Impedance Control register in the MPC8641D reference manual for more information
about local bus signals and their drive strength programmability.
3. See Section 17, “Signal Listings” for details on resistor requirements for the calibration of SD
n_IMP_CAL_TX and
SD
n_IMP_CAL_RX transmit and receive signals.
4. Stub Series Terminated Logic (SSTL-25) type pins.
5. Stub Series Terminated Logic (SSTL-18) type pins.
6. Low Voltage Transistor-Transistor Logic (LVTTL) type pins.
7. Open Drain type pins.
8. Low Voltage Differential Signaling (LVDS) type pins.
9. The drive strength of the DDR interface in half strength mode is at Tj = 105C and at Dn_GVDD (min).
