K60程序的一些问题。

我我用K60，八位拨码开关。但是没起作用。不知道哪出问题了？程序如下。各位指点一下
unsigned char  ReadSwitch(void)                           
{
unsigned char value = 0;
unsigned char swNumlow = 0;
unsigned char swNumhigh = 0;

swNumlow =  (PTD->PDIR & 0x00000080);
swNumlow |= (PTD->PDIR & 0x00000100);
swNumlow |= (PTD->PDIR & 0x00000200);
swNumlow |= (PTD->PDIR & 0x00000400);  
    swNumlow = swNumlow >> 7;
swNumhigh =  (PTD->PDIR & 0x00000800);
swNumhigh |= (PTD->PDIR & 0x00001000);
swNumhigh |= (PTD->PDIR & 0x00002000);
swNumhigh |= (PTD->PDIR & 0x00004000);
swNumhigh = swNumhigh >> 11;
value = swNumlow|swNumhigh;
    return (value);
}
调用的时候是switchState = ReadSwitch();
  if(switchState & 0x80)
   { led_turn1(led7);}

有什么问题么？？？？求指点
