The next SLIC interrupt which occurs, if unmasked, will indicate the end of the request message frame and
will either indicate that the frame was properly transmitted or that an error was encountered during
transmission. Refer to
explanation of these possible errors. This interrupt also signals to the application that the message frame
is complete and all data bytes and the checksum value have been properly transmitted onto the bus.
