I am trying to connect the st10f269 to a DUART froom Philips. The Duart accepts 8 bits which will come from the 16-bit data bus of the st10. The question is which Bits should be connected to the DUART. There is the obvious Software Solution to shift all characters i write so that the data to transmit is in the lower 8 bits, but i was wondering if there is a better solution. Any Ideas or hints are very appreciated.
