@par 例程描述 

本例程演示如何配置TIM外设生成四路不同延时的信号。\n
系统时钟工作在72Mhz，通过PLL配置产生。PLL时钟源是外部12Mhz晶振。APB1的分频比是1，APB2的分频比是1。\n

TIM1CLK 频率设置为 SystemCoreClock (Hz)。目的是获得1MHz的TIM1计数器时钟，因此预分频器的计算如下:\n
   - Prescaler = (72000000 / 1000000) - 1\n

TIM1 CCR1 寄存器值设为 800:\n
TIM1_CH1 delay = CCR1_Val / TIM1 counter clock  = 800 us \n
所以TIM1channel1生成延时为800us延时的信号。\n

TIM1 CCR2 寄存器值设为 400:\n
TIM1_CH2 delay = CCR2_Val / TIM1 counter clock  = 400 us \n
所以TIM1 Channel2生成延时为400us延时的信号。\n

TIM1 CCR3 寄存器值设为 200:
TIM1_CH3 delay = CCR3_Val / TIM1 counter clock  = 200 us \n
所以TIM1 Channel3生成延时为200us延时的信号。\n

TIM1 CCR4 寄存器值设为 100:\n
TIM1_CH4 delay = CCR4_Val / TIM1 counter clock  = 100 us \n
所以TIM1 Channel4生成延时为100us延时的信号。\n
