Macro Definition 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.

#define NULL   0L

Default NULL constant.

Typedef Documentation

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.

typedef void( linefunc68_t) (int, int)

First level (16 lines) decoder function.

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.
