The Asynchronous / Synchr. Serial Interface
For multiple back-to-back transfers it is necessary to load the next piece of data at last
until the time the last bit of the previous frame has been transmitted. In asynchronous
mode this leaves just one bit-time for the handler to respond to the transmitter interrupt
request, in synchronous mode it is impossible at all.
Using the transmit buffer interrupt (S0TBIR) to reload transmit data gives the time to
transmit a complete frame for the service routine, as TBUF may be reload while the
previous data is still being transmitted.
