利用附上的代码，实现与AD7147通信成功，但在AD7147的conversion sequence里面配置了12个stage运行，然后出来的结果只有stage0是有值的，从其他stage寄存器读出的值均为0。针对AD7147芯片手册重新配置了一遍AD7147，结果还是依旧，很迷惑。求高手解决！

配置描述：
寄存器2配置：
stage0   --CIN0(+)
stage1   --CIN1(+)
stage2   --CIN0(+)
stage3   --CIN3(+)
stage4   --CIN4(+)
stage5   --CIN5(+)
stage6   --CIN6(+)
stage7   --CIN7(+)
stage8   --CIN8(+)
stage9   --CIN9(+)
stage10   --CIN10(+)
stage11   --CIN11(+)
