ADS1258,CLKIO没有输出

ADS1258,CLKSEL置低,START PWDN都置高,其他都是按手册来处理的,现在6块板子就一块板子有输出的,而且也只有2,4,6,8通道有输出(8路差分),其他通道读出来都是0,有没有大神知道这个问题如何解决?
  • Clock Select Input: Low = Activates Crystal Oscillator, fCLK output on CLKIO.CLKSEL置低后,fCLK output on CLKIO 有无量到正确的clock信号呢?

    Reset Input: Hold low for minimum of two fCLK cycles to reset the device.

    CS,DRDY等pin以及POWER等都检查并且设定正确了?
