Receive Error (mode2)
If CF622 operates in mode 2, CF622 communicate fixed length data. Since the error data is not
counted as a data length, if CF622 runs continuous data communication, there is a possibility that the
deviation of the data is generated. Build user's application so as not to be the erroneous data by error
handling (ex. to generate time-out shown as Fig. 5-23).
