10 Register description
Register description
The device contains a set of registers which are used to control its behavior and to retrieve
linear acceleration, angular rate and temperature data. The register addresses, made up of
7 bits, are used to identify them and to write the data through the serial interface.

Table 20. FUNC_CFG_ACCESS register description
Enable access to the embedded functions configuration registers ⁽¹⁾ from address
02h to 32h. Default value: 0.
(0: disable access to embedded functions configuration registers;
1: enable access to embedded functions configuration registers)
1. The embedded functions configuration registers details are available in 11: Embedded functions register
mapping and 12: Embedded functions registers description.
