can
only be accessed in the
Configuration Mode and after the CSR has been
initialized to 1EH.
The default value of this
register after power up is 80H. This register is
used to select the base address of the Game
Chip Select decoder (GAMECS). The GAMECS
can be set to 48 locations, on 16 byte
boundaries from 100H-3F0H.
To disable the
GAMECS, set DB1 and DB0 to zero.
