3.2 Non-volatile memory
3.3 Output Registers

Add. is the register address in hex format.
RW – Read / Write register, R – Read-only register, NV – Register mirrors NV-memory data (NV = non-volatile).
IA – indirect addressing used.
Registers whose read and write access is blocked by register lock is marked in "Locked" column.
The SCA3000 has an internal non-volatile memory for calibration and configuration data. Memory
content will be programmed during production and is not user configurable. Initial configuration
values can be found in the following section 3.4.
The SCA3000 output registers (marked with 'Output' in Table 5) contents and bit definitions are
described in this section. Output registers contain information of measured acceleration and
temperature as well as information of the operating state and interrupts of SCA3000.
When reading the output values an MSB register must be read first because MSB register reading
latches the data in to all other acceleration output registers
