Serial Data Output
The serial data is output two times from SDO pin on each A/D conversion
cycle. The data format satisfy JIS 7BIT transmission code and the baud rate is
2400, it means the receiver terminal can use RS-232 interface to read data.

LSB
A single package include a start bit (0), D0~D6 (7 bit), a parity check
bit (odd) and a stop bit (1). All the data stream is consist of 110× 2 bits. The
high and low voltage levels correspond to DGND and V- respectively. SDO
remains at 1 (high) when it is inactive. Hence the Start bit (0) could be used as
the triggering signal to begin the reading process.
