//锁存74HC573信号为定义 扫描字符段。11脚当为高电平时移位，低电平锁存控制 9脚输出使

能端，低电平有效
sbit D3CS=P2^0;//输出扫描3组3位数码管 分别是cal/incline、speed、pause\distance
sbit D2CS=P1^5;  //输出控制扫描一个4位数码管。显示TIMER窗口

sbit D0CS=P2^1;  //74HC573输出控制8*8点阵窗口左上
sbit D1CS=P2^6;   //74HC573输出控制8**点阵窗口左下
sbit D4CS=P2^3;   //74HC573输出控制8**点阵窗口右上
sbit D5CS=P2^5;   //74HC573输出控制8**点阵窗口左下
//控制数码管位点阵列
