CHAPTER 7: DISASSEMBLER
S5U1C63000A MANUAL EPSON 111
(S1C63 FAMILY ASSEMBLER PACKAGE)
CHAPTER 7DISASSEMBLER
This chapter describes the functions of the disassembler, ds63.
7.1 Functions
The disassembler's input is an object in IEEE-695 or Motorola-S format. The code in the object file is
disassembled into mnemonics, and output as a source file. The restored source file can be processed in
the assembler/linker/hex converter to obtain the same object or hex file.

7.2.1 Input Files
Absolute object file
File format: Binary file in IEEE-695 format
File name: <File name>.abs (A path can also be specified)
Description: Absolute object file created by the linker
Hex file
File format: Text file in Motorola-S format
File name: <File name>.hsa, <File name>.lsa and <File name>.csa
Description: Hex files created by the hex converter. Three hex files are needed: ".hsa" that con-
tains the four high-order bits of the object codes with 0b000 extended, ".lsa" that
contains the eight low-order bits and ".csa" that contains four-bit data for the data
ROM. If there is no data ROM, the ".csa" file is not required.
7.2.2 Output Files
Source file
File format: Text file
File name: <File name>.ms
Output destination: Current directory
Description: Disassembled contents of the input file are delivered.
Error file
File format: Text file
File name: ds63.err
Output destination: Current directory
Description: The file is created if the -e start-up option is specified. It records the information that
the disassembler outputs to the Standard Output (stdout), such as error messages.
The file name is "ds63.err" by default, but it can be changed using the -o start-up
option.
