This register contains the calculated 16-bit arithmetic checksum over critical configuration and calibration registers.
It is updated on every DSP cycle. In use, the administrative processor records the value in the CHKSUM register and
then checks it periodically to verify that no configuration or calibration registers have changed. The MAXQ3183 sets
the CHSCH bit when this register’s value changes.
The registers included in the checksum calculation include the following:
