1.首先在.cmd中定位系统中断表：

MEMORY

{

PAGE 0 :

......................................

PAGE 1 :

......................................

PIE_VECT : origin = 0x000D00, length = 0x000100

......................................

}

SECTIONS

{

...................................

PieVectTable : > PIE_VECT, PAGE = 1

.....................................

}

2.在C中制定该中断的结构体：

#pragma DATA_SECTION(PieVectTable,"PieVectTable");

struct PIE_VECT_TABLE PieVectTable;（在DSP28_GlobalVariableDefs.C中初始化）

3.用一组常数（按照中断向量的顺序）初始化该名字为PIE_VECT_TABLE的表：

typedef interrupt void(*PINT)(void);这里有些一问，一下应该为函数名？？

// Define Vector Table:

struct PIE_VECT_TABLE {

// Reset is never fetched from this table.

// It will always be fetched from 0x3FFFC0 in either

// boot ROM or XINTF Zone 7 depending on the state of

// the XMP/MC input signal. On the F2810 it is always

// fetched from boot ROM.

PINT PIE1_RESERVED;

PINT PIE2_RESERVED;

PINT PIE3_RESERVED;

PINT PIE4_RESERVED;

PINT PIE5_RESERVED;

PINT PIE6_RESERVED;

PINT PIE7_RESERVED;

PINT PIE8_RESERVED;

PINT PIE9_RESERVED;

PINT PIE10_RESERVED;

PINT PIE11_RESERVED;

PINT PIE12_RESERVED;

PINT PIE13_RESERVED;

// Non-Peripheral Interrupts:

PINT XINT13; // XINT13

PINT TINT2; // CPU-Timer2

PINT DATALOG; // Datalogging interrupt

PINT RTOSINT; // RTOS interrupt

PINT EMUINT; // Emulation interrupt

PINT XNMI; // Non-maskable interrupt

PINT ILLEGAL; // Illegal operation TRAP

PINT USER0; // User Defined trap 0

PINT USER1; // User Defined trap 1

PINT USER2; // User Defined trap 2

PINT USER3; // User Defined trap 3

PINT USER4; // User Defined trap 4

PINT USER5; // User Defined trap 5

PINT USER6; // User Defined trap 6

PINT USER7; // User Defined trap 7

PINT USER8; // User Defined trap 8

PINT USER9; // User Defined trap 9

PINT USER10; // User Defined trap 10

PINT USER11; // User Defined trap 11

// Group 1 PIE Peripheral Vectors:

PINT PDPINTA; // EV-A

PINT PDPINTB; // EV-B

PINT rsvd1_3;

PINT XINT1;

PINT XINT2;

PINT ADCINT; // ADC

PINT TINT0; // Timer 0

PINT WAKEINT; // WD

.............

.............

// Group 12 PIE Peripheral Vectors:

PINT rsvd12_1;

PINT rsvd12_2;

PINT rsvd12_3;

PINT rsvd12_4;

PINT rsvd12_5;

PINT rsvd12_6;

PINT rsvd12_7;

PINT rsvd12_8;

};

然后在使我们在.cmd文件中定义的表有以上属性：

extern struct PIE_VECT_TABLE PieVectTable;(在.h文件中）

4.初始化该表（在.c文件中）使之能够为主程序所使用：

const struct PIE_VECT_TABLE PieVectTableInit = {

PIE_RESERVED, // Reserved space

PIE_RESERVED,

PIE_RESERVED,

PIE_RESERVED,

PIE_RESERVED,

PIE_RESERVED,

PIE_RESERVED,

PIE_RESERVED,

PIE_RESERVED,

PIE_RESERVED,

PIE_RESERVED,

PIE_RESERVED,

PIE_RESERVED,

// Non-Peripheral Interrupts

INT13_ISR, // XINT13 or CPU-Timer 1

INT14_ISR, // CPU-Timer2

DATALOG_ISR, // Datalogging interrupt

RTOSINT_ISR, // RTOS interrupt

EMUINT_ISR, // Emulation interrupt

NMI_ISR, // Non-maskable interrupt

ILLEGAL_ISR, // Illegal operation TRAP

USER0_ISR, // User Defined trap 0

USER1_ISR, // User Defined trap 1

USER2_ISR, // User Defined trap 2

USER3_ISR, // User Defined trap 3

USER4_ISR, // User Defined trap 4

USER5_ISR, // User Defined trap 5

USER6_ISR, // User Defined trap 6

USER7_ISR, // User Defined trap 7

USER8_ISR, // User Defined trap 8

USER9_ISR, // User Defined trap 9

USER10_ISR, // User Defined trap 10

USER11_ISR, // User Defined trap 11

// Group 1 PIE Vectors

PDPINTA_ISR, // EV-A

PDPINTB_ISR, // EV-B

rsvd_ISR,

XINT1_ISR,

XINT2_ISR,

ADCINT_ISR, // ADC

TINT0_ISR, // Timer 0

WAKEINT_ISR, // WD

.............

.............

// Group 12 E Vectors

rsvd_ISR,

rsvd_ISR,

rsvd_ISR,

rsvd_ISR,

rsvd_ISR,

rsvd_ISR,

rsvd_ISR,

rsvd_ISR,

};

//---------------------------------------------------------------------------

// InitPieVectTable:

//---------------------------------------------------------------------------

// This function initializes the PIE vector table to a known state.

// This function must be executed after boot time.

//

void InitPieVectTable(void)

{

int16 i;

Uint32 *Source = (void *) &PieVectTableInit;

Uint32 *Dest = (void *) &PieVectTable;

EALLOW;

for(i=0; i < 128; i++)

*Dest++ = *Source++;

EDIS;

// Enable the PIE Vector Table

PieCtrl.PIECRTL.bit.ENPIE = 1;

}

5.中断服务程序：

让以上的数值指向你所要的服务程序，例如：

PieVectTable.TINT2 = &ISRTimer2;

那么，ISRTimer2也就成了中断服务程序，

×××切记：一定要在主程序的开始先声明该程序：

interrupt void ISRTimer2(void);

.............

.............

然后按照您的需要编制该程序：

interrupt void ISRTimer2(void)

{

CpuTimer2.InterruptCount++;
