for example,inst390.uv2 project in the C:\Keil\C51\EXAMPLES\Dallas 390\Asm,in disassembly window ,the first instruction is displayed as "c:0x000000 020003 LJMP RESET(c:0003)" with source code : DB 02H ; LJMP in Classic 8051 Mode DW WORD0 Reset if "ljmp Reset",it is displayed as "c:0x000000 020000". why ljmp displayed in such a way in classic 8051 mode without ACON set?
