Standard Application Example

A typical non-code-banking application with the following memory map:

Memory Area	Address Range	Usage
On-Chip RAM	I:0x00–I:0xFF	Registers, bits, variables, stack, ...
External RAM	X:0x0000–X:0xFFFF	External variables.
External RAM	X:0x000000–X:0x01FFFF	Far variables.
ROM	C:0x0000–C:0xFFFF	Program code and constants.
ROM	C:0x000000–C:0x0FFFFF	Constants.

requires the following linker command line:

LX51 MYPROG.OBJ &
     CLASSES ( &
             HDATA  (X:0x000000 – X:0x01FFFF), &
             HCONST (C:0x000000 – C:0x0FFFFF) &
             )

Note

The address ranges for BIT, CODE, CONST, DATA, IDATA, and XDATA memory classes in the above linker command line are not required since the default settings cover the correct physical address ranges.
