CC1110数据的传输步骤如下:
1) strobe STX
2) 等待 RFTXRXIF 的值来判定可以向RFD写入1
3) 清除 RFTXRXIF
4) 写数据到 RFD
5) 从步骤2开始重复，直到写入最后1byte
6) 在最后1byte 写入 RFD之后, 等待IRQ_DONE的值来确认该packet被完全传输成功
您可以参考下附件内的程序，希望对您有所帮助！

Susan Yang，您好！你发的程序，是用DMA的方式，我需要用非DMA的方式来实现，现在遇到的问题就是RFTXRXIF 不产生。能收到一组数据包后就不再置1了。我这个代码也是在http://e2e.ti.com/上找的。不知道是不是非DMA的方式无法实现接收，官方例程也没有非DMA的例子。
