DATA (DIN/DOUT). Data transfer is initiated by a falling chip
select (CS) signal. After CS falls, the LTC1291 looks for a
start bit. After the start bit is received, a 4-bit input word
is shifted into the DIN input which configures the LTC1291
and starts the conversion. After one null bit, the result of
the conversion appears MSB-first on the DOUT line. The
conversion result is output, bit by bit, as the conversion is
performed. At the end of the data exchange, CS should be
brought high. This resets the LTC1291 in preparation for
the next data exchange.
