我使用的F2806x_CpuTimers.c文件中的标准函数
void ConfigCpuTimer(struct CPUTIMER_VARS *Timer, float Freq, float Period)
{
Uint32 PeriodInClocks;
// Initialize timer period:
Timer->CPUFreqInMHz = Freq;
Timer->PeriodInUSec = Period;
PeriodInClocks = (long) (Freq * Period);
Timer->RegsAddr->PRD.all = PeriodInClocks - 1; // Counter decrements PRD+1 times each period
// Set pre-scale counter to divide by 1 (SYSCLKOUT):
Timer->RegsAddr->TPR.all = 0;
Timer->RegsAddr->TPRH.all = 0;
// Initialize timer control register:
Timer->RegsAddr->TCR.bit.TSS = 1; // 1 = Stop timer, 0 = Start/Restart Timer
Timer->RegsAddr->TCR.bit.TRB = 1; // 1 = reload timer
Timer->RegsAddr->TCR.bit.SOFT = 0;
Timer->RegsAddr->TCR.bit.FREE = 0; // Timer Free Run Disabled
Timer->RegsAddr->TCR.bit.TIE = 1; // 0 = Disable/ 1 = Enable Timer Interrupt
// Reset interrupt counter:
Timer->InterruptCount = 0;
}
程序执行时在变量窗口里面看不到Timer->RegsAddr->PRD.all 的值？单步执行时会直接跳过Timer->RegsAddr->PRD.all = PeriodInClocks - 1;这一步，好像这一步没执行，我用的系统时钟频率80M，调用函数时设置Freq值为40， Period值为8000，用的80管脚的28069片子
