如果f2812的时钟频率是150MHz试根据周期寄存器和预定标寄存器的取值范围计算CPU定时器0可

源程序如下：
//就是通过这个循环来实现信号的输入
while(1)
{
GpioDataRegs.GPADAT.all =0xAAAA;
GpioDataRegs.GPBDAT.all =0xAAAA;
GpioDataRegs.GPDDAT.all =0x0022;
GpioDataRegs.GPEDAT.all =0x0002;
GpioDataRegs.GPFDAT.all =0xAAAA;
GpioDataRegs.GPGDAT.all =0x0020;
delay_loop();//´ËÐÐÌí¼Ó¶Ïµã

GpioDataRegs.GPADAT.all =0x5555;
GpioDataRegs.GPBDAT.all =0x5555;
GpioDataRegs.GPDDAT.all =0x0041; // Four I/Os only
GpioDataRegs.GPEDAT.all =0x0005; // ThreeI/Os only
GpioDataRegs.GPFDAT.all =0x5555;
GpioDataRegs.GPGDAT.all =0x0010; // Two I/Os only
