    • The wireless communication device of the present invention is provided with a received data FIFO for temporarily storing received data, and a data reading section for reading received data from the received data FIFO. The data reading section, when received data to be read is stored in the received data FIFO, reads and outputs the stored received data. Meanwhile, when the received data to be read is not stored in the received data FIFO and a predetermined condition is fulfilled, the data reading section outputs dummy received data. Furthermore, when the received data to be read is not stored in the received data FIFO and the predetermined condition is not fulfilled, the data reading section outputs an error.
    • 本发明的无线通信装置设置有用于临时存储接收数据的接收数据FIFO,以及用于从接收数据FIFO读取接收数据的数据读取部分。 当接收到的要被读取的数据被存储在接收数据FIFO中时,数据读取部分读出并输出存储的接收数据。 同时,当接收到的要被读取的数据不存储在接收数据FIFO中并且满足预定条件时,数据读取部输出虚拟接收数据。 此外,当接收到的要被读取的数据未被存储在接收数据FIFO中并且不满足预定条件时,数据读取部输出错误。
