ADDRESS CONFIGURATION
The SB-3611X card requires that the user program the base
address by setting jumpers and DIP switches on the card.
Before installing the SB-3611X card, refer to FIGURE 3 for DIP
Switch Configuration and FIGURE 4 for Reference Jumper
Selection.
The SB-3611X card can be operated in 16-, 24- or 32-bit
address modes (See FIGURE 2). Selection of the address mode
is set by two jumpers, JP1 (3) and JP1 (2), which when made
disable address lines A24-31 and A16-31 respectively and set
the AM0-5 combination to which the card will respond with the
selected address line combination. The card is in 32-bit address
mode when jumpers JP1 (2) and JP1 (3) are not installed.
Operation in protected mode is possible and is invoked by
installing jumper JP1 (1). When this jumper is connected, the
processor can only access the card when in supervisor mode;
otherwise the card can be accessed in either supervisor or user
mode.
The Address of the SB-3611X in the example shown in FIGURE
3 is set to HEX address 8000 (in 16-Bit address mode). The user
may choose from 0000 0000h to FFFF FF00h in 100 HEX incre-
ments.
