Memory access caller type

typedef u32(* memrfunc68_t )(u32 addr, cycle68_t cycle)
 Read memory function.
typedef void(* memwfunc68_t )(u32 addr, u32 value, cycle68_t cycle)
 Write memory function.

Defines

#define IO68_NO_INT   (0x80000000)
 IO no pending interruption return value.
#define NULL   0L
 Default NULL constant.
#define MEM68MSK   ((1<<19)-1)
 Mask for memory overflow.

Typedefs

typedef void( linefunc68_t )(int, int)
 First level (16 lines) decoder function.
typedef _io68_t io68_t
 IO emulator pluggin structure.


Define Documentation

#define IO68_NO_INT   (0x80000000)
 

IO no pending interruption return value.

The next_int function of IO plugin must return IO68_NO_INT when no interruption are expected.


Typedef Documentation

typedef struct _io68_t io68_t
 

IO emulator pluggin structure.

All 68K IO must have a filled io68_t structure to be warm plug or unplug with ioplug interface.
