CONVERSION SEQUENCE
A conversion can be started by sending the command to MS5607-02BA. When command is sent to the system it
stays busy until conversion is done. When conversion is finished the data can be accessed by sending a Read
command, when an acknowledge appears from the MS5607-02BA, 24 SCLK cycles may be sent to receive all
result bits. Every 8 bit the system waits for an acknowledge signal.

CYCLIC REDUNDANCY CHECK (CRC)
MS5607-02BA contains a PROM memory with 128-Bit. A 4-bit CRC has been implemented to check the data validity
in memory. The application note AN520 describes in detail CRC-4 code used.
