FL.NET module's unique feature
When the received transparent message TCD number is between 0 and 999, the reception
message data is handled as word data in little-endian format. However, if the reception
message data word count is expressed by an odd number of bytes, the data does not convert
normally into little-endian format. If the specified TCD number is other than the above, the
reception data is transferred as it is.

between 0 and 999 is received
