9.2.2
Here processing to prepare the environment for program execution is explained. However, the
environment for program execution will differ among user systems, and so a program to set the
execution environment must be created according to the specifications of the user system.
Figure 9.6 shows an example of the structure of a program.
The contents of each of the routines are as follows.
Vector table (VEC_TBL)
Sets the vector table such that the register initial settings program (PowerON_Reset) is started
up at power-on reset.
Initial settings (PowerON_Reset)
After initial register values are set, calls the initial setting routines in sequence.
Section initialization tables (DTBL, BTBL)
Uses the section address operator to set the leading and ending addresses for the section used
in the section initialization routine.
_ INITSCT
Note: Necessary when there is a global class object declaration in the C++ program.
