When measurements on all three axes are completed, a logic high level is output to the DRDY pin, indicating “measurement data
is ready.” The DRDY status can be monitored by the DRDY bit in Status Register (Address: $09). The DRDY pin is kept high until
one of the three Output Value Registers are read. If the next measurement data is written before the previous data is read, the
DOVR bit in the Status Register will be set. Also note that in measurement mode, level detection mode and pulse detection mode
are not available.
