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.
Data conversion effected when a transparent message having a TCD number
between 0 and 999 is received
Example: When 4-byte data is received
Data n
Data n+1
Byte-swapped on an individual word basis and then received.
Data n+1
Data n
5-82
Data n+2
