标题:
dsp2812 同时使用定时器0和2，遇到一些问题
  
    没有一起用过的经验 网上找了一些例子程序
发现用了之后 还是只有定时器0在工作 ，定时器2的中断根本没进去过 想知道原因
附上自己的程序：
#include "DSP281x_Device.h"
#include "example_nonBIOS.h"
#include "main.h"
#define StartCpuTimer0()  CpuTimer0Regs.TCR.bit.TSS = 0
#define StartCpuTimer2()  CpuTimer2Regs.TCR.bit.TSS = 0
void User_Init(void);
interrupt void cpu_timer0_isr(void);
interrupt void cpu_timer2_isr(void);
void main(void)
{
    /*** CPU Initialization ***/
    InitSysCtrl();  //Initialize the CPU (FILE: SysCtrl.c)
    DINT;
    IER = 0x0000; // Disable CPU interrupts
    IFR = 0x0000; // Clear all CPU interrupt flags
    InitXintf();  //Initialize the external memory interface (FILE: Xintf.c)
    //InitGpio();  // Initialize the shared GPIO pins (FILE: Gpio.c)
    InitPieCtrl();  // Initialize and enable the PIE (FILE: PieCtrl.c)
    InitEv();   // Initialize the EV(FILE: Ev.c)--And initialize the Timer1
    InitCpuTimers();
// Initialize the time (FILE: DSP281x_CpuTimers.c)
    //FFT();
     EALLOW;    // This is needed to write to EALLOW protected registers
    PieVectTable.TINT0 = &cpu_timer0_isr;//timer0中断服务子程序重定位
    PieVectTable.TINT2 = &cpu_timer2_isr;//timer0中断服务子程序重定位
    EDIS;      // This is needed to disable write to EALLOW protected registers
    IER |=(M_INT1|M_INT14);  // EV Interrupt
    IFR &= 0x0000;  //Clear all interrupt flag
    &nbsp
ieCtrlRegs.PIEIER1.bit.INTx7 = 1;// Enable TINT0 in the PIE: Group 1 interrupt 7
  
    //SetDBGIER(IER);  // Configure the DBGIER for realtime debug        
    EINT;    // Enable global interrupts and realtime debug
ERTM;
    //asm(" CLRC INTM, DBGM");
    StartCpuTimer0();
    StartCpuTimer2();
while(1)
{}
}
interrupt void cpu_timer0_isr(void)
{   
Count_AD++;
PieCtrlRegs.PIEACK.all = PIEACK_GROUP1;
    }
interrupt void cpu_timer2_isr(void)
{
  
  COUNT++;
 &nbsp
ieCtrlRegs.PIEACK.all = PIEACK_GROUP2;
}
