msp430 fr5994 改变全局变量或静态变量就会出现问题？

≪ Previous: MSP430F6638的ADC采用内部2.5V参考电压时，用ADC通道0（P6.0）读出数据准确，但是运用AD1或者AD2等其他通道不加电压读出值为4096，求大神帮看看程序是不是有问题？

#include <msp430.h>
#include "driverlib.h"
#include <clk16.h>

/**
* main.c
*/
uint8_t i=0;
void main(void)
{
clk16();
Timer_A_clearTimerInterrupt(TIMER_A0_BASE);
Timer_A_initUpModeParam param;
param.clockSource=TIMER_A_CLOCKSOURCE_SMCLK;
param.clockSourceDivider=TIMER_A_CLOCKSOURCE_DIVIDER_32;
param.timerPeriod=50000;
param.captureCompareInterruptEnable_CCR0_CCIE=TIMER_A_CCIE_CCR0_INTERRUPT_ENABLE;
param.timerClear=TIMER_A_DO_CLEAR;
param.startTimer=false;

i=3;

Timer_A_initUpMode(TIMER_A0_BASE,&param);
GPIO_setAsOutputPin(GPIO_PORT_P1,GPIO_PIN0);
Timer_A_startCounter(TIMER_A0_BASE,
TIMER_A_CONTINUOUS_MODE
);
__bis_SR_register(LPM0_bits + GIE);

}

#pragma vector = TIMER0_A0_VECTOR
__interrupt
void Timer_A0_ISR(void)
{

if(Timer_A_getInterruptStatus(TIMER_A0_BASE))
{

GPIO_setOutputHighOnPin(GPIO_PORT_P1,GPIO_PIN2);

Timer_A_clearTimerInterrupt(TIMER_A0_BASE);
}

}

如上代码，i=3存在，则debug 打断点无法进入定时器中断，删掉i=3，则可以进入中断

感觉430的中断向量有点乱，TIMER_A1_BASE 中断向量却显示TA0,下面的宏定义 A5又是什么意思，中断向量是怎么分配的？

#define TIMER0_A1_VECTOR (53u * 2u) /* 0xFFEA Timer0_A5 CC1-4, TA */
#define TIMER0_A0_VECTOR (54u * 2u) /* 0xFFEC Timer0_A5 CC0 */

当我在使用ccs9.1添加头文件时总是出现各种各样的问题，例如在创建一个名为LCDTEST新工程时，为它中添加 OutOfBox_MSP430FR6989例程中的hal_LCD.c与hal_LCD.h时编译总会出现各种问题，但如果把main.c中的代码放到 OutOfBox_MSP430FR6989例程当中就不会出现问题。我想要知道应该如何为一个新工程添加头文件，我已经尝试过http://processors.wiki.ti.com/index.php/Include_paths_and_options中的方法，仍然行不通，请尽可能完整的演示一下应该如何为一个新工厂添加头文件，谢谢
