This chapter describes the functions of the linker, lk63.
5.1 Functions
The linker lk63 is a software that generates executable object files. It provides the following functions:
• Puts together multiple object modules to create one executable object file.
• Resolves external reference from one module to another.
• Relocates relative addresses to absolute addresses.
• Delivers debugging information, such as line numbers and symbol information, in the object file
created after linking.
• Capable of outputting a link map file, symbol file, absolute list file and a cross reference file.
• Automatic page correction function (insertion/removal/correction of the "ldb %ext, imm8" branch
extension instruction) for branch instructions.

line. This file is dispensable if all start-up options can be input in a command line.
ICE parameter file ∗
This file must always be specified in either a command line or a link command file.
File format: Binary file
File name: .par (A path can also be specified.)
Description: File to specify the memory mapping and unsupported instruction information of each
