Functions | |
void | EMU68memory_init (void) |
Init memory quick access table. | |
void | EMU68memory_reset (void) |
Reset memory quick access table. | |
void | EMU68memory_new_area (u8 area, memrfunc68_t *read_bwl, memwfunc68_t *write_bwl) |
Add a new memory access control area (for new IO). | |
void | EMU68memory_reset_area (u8 area) |
Reset memory access control area to default state. |
|
Init memory quick access table. The EMU68memory_init() function must be call at init time. Currently this function only call the EMU68memory_reset() function.
|
|
Reset memory quick access table. The EMU68memory_reset() function restores all memory access to default. All mapped IO will be discard and replace by onboard memory access. |
