(四)GTM_TOM模块定时器中断应用

---

功能：

**定时1ms的中断（使用GTM模块的子单元TOM0模块），借助LED检测，分别300ms 500ms间隔闪烁2个LED **

基于iLLD库，跟外设GTM模块的子模块TOM相关的基本都在：

#include "IfxGtm_Tom_Timer.h"
#include "IfxGtm.h"
#include "IfxGtm_Cmu.h" 

interrupt.c文件：

#include "Interrupt.h"
#include "IfxGtm_Tom_Timer.h"
#include "IfxPort.h"
#include "Blinky_LED.h"

#define ISR_PRIORITY_TOM    9                       /* Interrupt priority number                                    */
#define TOM_FREQ            1000.0f                    /* TOM frequency                                                */


short one_sec_flag = 0;

IfxGtm_Tom_Timer g_timerDriver; //类似linux文件句柄

/* Macro to define the Interrupt Service Routine. */
IFX_INTERRUPT(interruptGtmTom, 0, ISR_PRIORITY_TOM);
/* Interrupt Service Routine of the TOM */
void interruptGtmTom(void)
{
   
    static int i,j,one_sec = 0;
    IfxGtm_Tom_Timer_acknowledgeTimerIrq(&g_timerDriver);                       /* Clear the timer event            */
