Freescale MC9S12G128 interrupt code implementation method-EEWORLD

Writing method 1:

The interrupt function specifies the interrupt vector number:

main.c

#pragma CODE_SEG __NEAR_SEG NON_BANKED

interrupt interrupt vector number void interrupt service function name (void) {

//Interrupt service routine code segment

}

#pragma CODE_SEG DEFAULT

The interrupt vector number is defined in the mc9s12g128.h file, such as:

/**************** interrupt vector numbers ****************/

#define VectorNumber_Vportj 24U

Writing method 2:

Modify the prm file and declare the interrupt function in the Project.prm file:

main.c:

#pragma CODE_SEG __NEAR_SEG NON_BANKED

interrupt void interrupt service function name (void) {

//Interrupt service routine code segment

}

#pragma CODE_SEG DEFAULT

Project.prm:

Add VECTOR ADDRESS interrupt vector interrupt service function name at the end of the file

For example: ProtJ interrupt vector: 0xFFCE, interrupt function name: PTJ_IRQ

VECTOR ADDRESS 0xFFCE PTJ_IRQ

The interrupt vector is defined in the mc9s12g128.h file, such as:

/**************** interrupt vector table ****************/

#define Vportj 0xFFCEU
