The MMA62XXKEG is trimmed to provide the most accurate voltage representation of acceleration at X
done by adjusting the signal within the DSP to compensate for errors within the digital-to-analog converters. The SPI is disabled
when the device is in normal operating mode, and dedicated ST (self-test activation) and STATUS pin functions are assigned.
