Hi,

perhaps try to find out if your protocol allows you to manipulate the tx
fifo (esp. turn it off). If yes, then do so. Now the TEMT signal will tell
you that there is at most one more byte to be sent, and you can be sure to
switch at the 'right' time if the last byte is an insignificant 0xFF.
Delay in software by 1 bit time or more after TEMT to allow the start
bit to go out w/o glitch. This is a hack, but it is a hack that worked for
me.

Peter
