单片机里面有辣么多定时器，我先不看其它的，要不然我直接晕菜。其实人生就是一个main(){}。
When I was born in ****/**/**, I was powered on.
When I was 18 years old, I was initialized.
Then I entered a loop for:
for(;;)
{
起床;早饭;上班;午饭;拍打;下班;晚饭;碎觉;
}
Where is the Break; sentence? No Break; No Hope. But I'd like to say it's perfect life for ordinary people.
12 位间隔定时器的运行时序
以ITCMP11 ～ ITCMP0 位设定的计数值为间隔，作为重复产生中断请求（INTIT）的12 位间隔定时器运行。如果将RINTE 位置“1”， 12 位计数器就开始计数。当12 位计数器的值和ITCMP11 ～ ITCMP0 位的设定值相同时，将12 位计数器清“0” 并且继续进行计数，同时产生中断请求信号（INTIT）。
(1499 +1) * 1/15 = 100ms
(3276 +1) * 1/32.768 = 100ms
