I am trying to silmulate the 7segment& stepper motor with 8086mp using proteus.Program compled succesfully but when iam running it schematic capture iam getting an error called program load address is beyond the internal memory range which i couldn't understood.Kindly waiting for a quick answer.
The 8086 starts execution at
0xFFFF:0000, which is only 16 bytes before end of address space.
You as a developer are supposed to put a jump instruction there to point the program counter at the actual program start.
If the PC just continues incrementing, you get a wrap-around at
FFFF:0010. The behaviour here differes between chip versions, the original 8086 wraps to
0000:0000, while modern variants (80286 and up) would access memory beyond 1MB. See also "A20 gate".
In most cases using addresses bigger than
FFFF:000F will be a bug. Don't do that.
