AIC-6915 Ethernet LAN Controller Programmer's Manual AIC-6915 Functional Registers Summary Mapped to address range 0x50040-0x500FF in memory space, address 0x40-0xFF in configuration space and address 0x40-0xFF in I/O space. These registers are read/write and can be accessed using Memory, I/O, and Configuration commands. Table 6-2.
