本程序是飞思卡尔HCS908_QG8PWM模块的例程，所用资源为单片机内部TPM模块，所接器件为LED. LED的闪烁频率逐渐减小，直到熄灭，然后再次点亮，如此循环熄灭点亮！-This procedure is the PWM module s routines, and resources for the internal microcontroller TPM module, the access device for LED LED flicker frequency decreases gradually until extinguished, and then light up again, so the cycle turns off light!
