Output Data Registers
5.3
Output data registers hold the sensor information as it is measured; they are overwritten
only when new data is available. Table 21 lists each register, its memory address, and its
conversion factor. Note: the scale-factor described below only applies to the values in
the data registers and standard burst-mode. Scale-factors for the other output data
packets follow the values listed in Section 7.4.

System Registers
5.4
In addition to the output data registers, there are further read-only registers that provide
DMU380ZA system information to the SPI master. Table 22 provides a description of
each along with their read-addresses.
