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.

10.1

FUNC_CFG_ACCESS (01h)

Enable embedded functions register (r/w).

Table 20. FUNC_CFG_ACCESS register description

10.2

SENSOR_SYNC_TIME_FRAME (04h)

Sensor synchronization time frame register (r/w).

Table 22. SENSOR_SYNC_TIME_FRAME register description

10.3

SENSOR_SYNC_RES_RATIO (05h)

Sensor synchronization resolution ratio (r/w)

Table 19. FUNC_CFG_ACCESS register

FUNC_CFG_EN

0(1)

1. This bit must be set to ‘0’ for the correct operation of the device.

0(1)

FUNC_CFG_EN

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.

Table 21. SENSOR_SYNC_TIME_FRAME register

0(1)

1. This bit must be set to ‘0’ for the correct operation of the device.

0(1)

TPH_3

TPH_2

TPH_1

TPH_0

TPH_ [3:0]

Sensor synchronization time frame with the step of 500 ms and full range of 5 s.

Unsigned 8-bit.

Default value: 0000 0000 (sensor sync disabled)

Table 23. SENSOR_SYNC_RES_RATIO register

0(1)

1. This bit must be set to ‘0’ for the correct operation of the device.
