The flag will turn ON when anything is
received after reception has been com-
pleted and execution of the next
RXD(235).
End Code Specified: The flag will turn
ON when anything is received after the
end code has been received and execu-
tion of the next RXD(235) or when the
257th byte of data is received before the
end code is received.
