7 The SASM Assembler
7 The SASM Assembler
This part of the manual describes the SASM assembler (integrated in the SX-Key Version 2.0 software)
which is an enhanced version of Ubicom’s SASM.
The SX-Key software 2.0 and above supports both assemblers, the Ubicom SASM which is described in
this chapter, and the Parallax Assembler which is described briefly in the next chapter.
Although you may select between both assemblers using the Configure dialog, it is highly suggested
that you design all new code for SASM, and use the Parallax Assembler for “old” source code only,
written under previous versions of the SX-Key software. You should even consider changing such code
so that is assembles under SASM, or both because there are only a few minor modifications necessary
for that purpose (see Chapter 9 – Upgrading Existing Code for SASM).
The main task of the assembler is to translate the contents of program source code files into code that
can be programmed into the SX device’s E²Flash memory, where it is then executed at run-time.
The assembler also generates various output files that will be described in Chapter 7.10 – Files created
by SASM.
