The device contains a set of registers which are used to control its behavior and to retrieve linear acceleration,

angular rate, temperature and Qvar 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 embedded functions register (R/W)

Table 24. FUNC_CFG_ACCESS register

EMB_FUNC_

REG_ACCESS

0(1)

FSM_WR_

CTRL_EN

SW_POR

0(1)

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

Table 25. FUNC_CFG_ACCESS register description

EMB_FUNC_REG_ACCESS

Enables access to the embedded functions configuration registers. (1)

Default value: 0

FSM_WR_CTRL_EN

Enables the control of the CTRL registers to FSM (FSM can change some configurations of the

device autonomously). Default value: 0

(0: disabled; 1: enabled)

SW_POR

Global reset of the device. Default value: 0

1. Details concerning the embedded functions configuration registers are available in Section 10 Embedded functions register

mapping and Section 11 Embedded functions register description.

9.2

PIN_CTRL (02h)

WCLK and SDO pin pull-up register (R/W). This register is not reset during the software reset procedure (see bit 0

of the CTRL3 (12h) register).

Table 26. PIN_CTRL register

TDM_WCLK

_PU_DIS

SDO_

PU_EN

IBHR_

POR_EN

0(1)

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 27. PIN_CTRL register description

TDM_WCLK_PU_DIS

Disables pull-up on WCLK pin. Default value: 0

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

SDO_PU_EN

Enables pull-up on SDO pin. Default value: 0

(0: SDO pin pull-up disconnected;

1: SDO pin with pull-up)

IBHR_POR_EN

Selects the action the device performs after "reset whole chip" I3C pattern. Default value: 1

(0: Configuration reset (SW reset + dynamic address reset);

(1: Global reset (POR reset))
