- * Warning: the PC value will not point to start of instruction (it will be middle or\r
- * end), also updating PC is dangerous, as Cyclone may internally increment the PC\r
- * before fetching the next instruction and continue executing at wrong location.\r
+ * MEMHANDLERS_NEED_PC updates .pc context field with PC value effective at the time\r
+ * when memhandler was called (opcode address + unknown amount).\r
+ * MEMHANDLERS_NEED_PREV_PC updates .prev_pc context field to currently executed\r
+ * opcode address + 2.\r
+ * Note that .pc and .prev_pc values are always real pointers to memory, so you must\r
+ * subtract .membase to get M68k PC value.\r
+ * Warning: updating PC in memhandlers is dangerous, as Cyclone may internally\r
