CHAPTER 3: SOFTWARE DEVELOPMENT PROCEDURES
The following shows the section definition of the sample program used in the tutorial as a simple example. Since
the assembly source program "boot.s" consists of only a program code, only the .code pseudo-instruction is used.
<boot.s>
<main.c>

(Program explanation)
(Program explanation)
Do not use this program in actual applications because the actual applications require setting up the
trap processing vector, etc.
The main( ) function is cleared global variable i to 0 because it is used as a counter. Then an endless
loop is created by local variable j, and the sub( ) function is called repeatedly by using j as the
argument. The sub( ) function increases global variable i by one every two calls.
Boot processing is performed to initialize the stack and global pointers, and call the main function.
