There is a sync serial driver but it hasn't been tested much in
slave mode. For slave input mode the pin assignment is:
ETRAX pin Sync ser pin
This means that the data pin aren't routed through
the RS-422 line drivers (txd and rxd are routed through
the drivers). So some soldering will be required if you
want to do this on a developer board.
I am completelty clueless about HDLC, is the clock signal
also transported over RS-422? Do you use one of the pairs
for this and the other for data?
