7. The CFG2 pin is not supported on the ÉlanSC410 microcontroller.
8. Memory Address MA11–MA4 Suspend state of the pins:
9. The ROM control signals have three programmable options for Suspend mode:
Summary: These pins have built-in pulldown resistors that are invoked by:

Will be three-stated with a pulldown resistor. This will work for CAS-before-RAS refresh, self-refresh, and the DRAM powered
down.
Summary: These pins have built-in pulldown resistors that are invoked by Suspend mode.
–Driven High (inactive)
–Three-stated with no pullup or pulldown. This is useful when the ROM is at 5 V and left powered in Suspend. The board
– Three-stated with pulldown resistors when suspended with the intent of powering off the ROMs (Power-Down Group B).
–Suspend mode; and the ROM interface is programmed to be powered off in Suspend mode (Power-Down Group B).
design should not drive 3.3-V signals into a 5-V device during Suspend, because this can waste power. The system
designer could provide large pullup resistors to 5 V for each of these signals on the board if this configuration is
programmed.
