17.5.12 Initialization routine information

The initialization routine information defines Attribute: iniatr, Extended information: exinf, Start address: inirtn for an initialization routine.

The number of initialization routine information items that can be specified is defined as being within the range of 0 to 254.

The following shows the idle initialization routine information format.

ATT_INI ({ initatr, exinf, inirtn });

The items constituting the initialization routine information are as follows.

1 ) Attribute: iniatr

Specifies the language used to describe an initialization routine.
The keyword that can be specified for iniatr is TA_HLNG or TA_ASM.

TA_HLNG: Start an initialization routine through a C language interface.

TA_ASM: Start an initialization routine through an assembly language interface.

2 ) Extended information: exinf

Specifies the extended information for an initialization routine.
A value from 0x0 to 0xffffffff, or a symbol name, can be specified for exinf.

Note The target initialization routine can be manipulated by handling the extended information as if it were a function parameter.

3 ) Start address: inirtn

Specifies the start address for an initialization routine.
A value from 0x0 to 0xfffffffe (aligned to a 2-byte boundary), or a symbol name, can be specified for inirtn.

Note When an initialization routine handler is coded as follows, the symbol name specified for inirtn should be func_ini.

#include <kernel.h> void func_ini ( VP_INT exinf ) { ............ ............ return; }
