DS1 Switch Settings—Controller

Memory Starting Address

The factory set controller memory starting address (hexadecimal) is 80000h. (The h is used to denote a hexadecimal number.)

The Dual In-line Package (DIP) switch designated DS1, SW8 through SW1 selects the base or starting address of RAM. The address range must be set such that it does not conflict with other RAM, ROM, or memory mapped I/O address in the PC system. This address range must be consistent with the software being used. Figure A-2 shows switch DS1 with the controller memory starting address set to the factory setting (80000h).
