请教几个CC1100的问题

我在做CC1100通讯的时候，状态位老是变化。具体变化是RX->IDLE->TX。还有读状态寄存器的话是不是要前面加|0XC0的？

附我的配置：

   CC1100WriteReg(CC1100_MCSM2 ,   0x0e);
   CC1100WriteReg(CC1100_MCSM1 ,   0x30);
   CC1100WriteReg(CC1100_MCSM0 ,   0x18);

循环程序为：

addr=CC1100ReadReg(CC1100_MARCSTATE);
 RFReceiveLen = CC1100ReadReg(CC1100_RXFIFO);
 CC1100ReadBurstReg(CC1100_RXFIFO, RFReceive_Buf, RFReceiveLen);  //保证下标不越界
 CC1100Strobe(CC1100_SFRX);                                                                                 //清除接收缓存
 readbiao_time=0;

ADDR的值 变化为0X1F->0X5F->0X2F 。

还有就是改成

RF_Sts_ToRX();

RFReceiveLen = CC1100ReadReg(CC1100_RXFIFO);
 CC1100ReadBurstReg(CC1100_RXFIFO, RFReceive_Buf, RFReceiveLen);  //保证下标不越界
 CC1100Strobe(CC1100_SFRX);                                                                                 //清除接收缓存
 readbiao_time=0;

明显清楚不了缓存
