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.

9.1

FUNC_CFG_ACCESS (01h)

Enable ISPU / sensor hub functions register (R/W)

Table 18. FUNC_CFG_ACCESS register

ISPU_REG

_ACCESS

SHUB_REG

_ACCESS

0(1)

SW_RESET

_ISPU

0(1)

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

Table 19. FUNC_CFG_ACCESS register description

ISPU_REG_ACCESS

Enables access to the ISPU interaction registers(1). Default value: 0

SHUB_REG_ACCESS Enables access to the sensor hub (I²C master) registers(2). Default value: 0

SW_RESET_ISPU

Software reset of ISPU core. Set the bit to 1 to activate the reset sequence and immediately write

back to 0 (this bit is not automatically cleared). Default value: 0

1. Details regarding the ISPU interaction registers are available in Section 10 ISPU interaction register mapping and

Section 11 ISPU interaction register description.

2. Details concerning the sensor hub registers are available in Section 14 Sensor hub register mapping and

Section 15 Sensor hub register description.

9.2

PIN_CTRL (02h)

SDO pin pull-up register (R/W)

Table 20. PIN_CTRL register

0(1)

SDO_PU_EN

1(2)

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

2. This bit must be set to 1 for the correct operation of the device.

Table 21. PIN_CTRL register description

SDO_PU_EN

Enables pull-up on SDO pin.

(0: SDO pin pull-up disconnected (default); 1: SDO pin with pull-up)
