#define GENERAL_IO                              0
// Direct I/O mode assumes the AX88796 address, data, and control lines are
// connected directly to processor I/O pins.  The memory-bus accesses are
// software emulated.
//
#define MEMORY_MAPPED                   1
// Memory-mapped mode assumes that the AX88796 is connected the processor via
// the external memory bus, and that the AX88796 address space starts at the
// memory location AX88796_MEMORY_MAPPED_OFFSET.
//
// In either mode, a seperate I/O pins is required for control of the AX88796's
// hardware RESET line.
