TRANSLATING ASSEMBLY CODE FROM HC05 TO ST7

4.3 LABELS

In order to be able to see all the labels from the emulator (in the disassembler window, a label

name is more significant than an address), it’s better to declare them all as public (a simple dot

placed before the label name).

For labels which are called from another module, create a .inc file to declare them as “EX-

TERN”:

appli.asm:

st7/

TITLE “appli.asm”

MOTOROLA

; Motorola format (default), other formats are

also available:

; Intel, Zilog or Texas.

#include “appli.inc”

; lib appli.s05

#include “variable.inc”

#include “constant.inc”

#include “ST72251.inc”; this is the map file (see below).
