CTRL4_C (13h)

Control register 4 (r/w).

BLE

Big/Little Endian Data Selection. Default value 0.

(0: data LSB @ lower address; 1: data MSB @ lower address)

SW_RESET

Software Reset. Default value: 0.

(0: normal mode; 1: reset device)

This bit is cleared by hardware after next flash boot.

1. Boot request is executed as soon as internal oscillator is turned on. It is possible to set bit while in power-

down mode, in this case it will be served at the next normal mode or sleep mode.

Table 50. CTRL4_C register description

XL_LP_EN

Accelerometer low-power/normal mode enable. Default value: 0.

(0: normal mode; 1: low-power mode with ODR

 100Hz)

SLEEP_G

Gyroscope sleep mode enable. Default value: 0.

(0: disabled; 1: enabled)

FIFO_TEMP_EN Temperature data storing in FIFO enable. Default value: 0.

(0: temperature data not stored in FIFO; 1: temperature data stored in FIFO)

DRDY_mask_bit

_CFG1

Configuration 1(1) Data Available Enable bit. Default value: 0.

(0: DA timer disabled; 1: DA timer enabled)

1. In Configuration 1, switching to Combo mode, data are collected in FIFO only when both the accelerometer

and gyroscope are set. Switching to accelerometer-only, data are collected in FIFO after filter setting.

I2C_disable

Disable I2C interface. Default value: 0.

(0: both I2C and SPI enabled; 1: I2C disabled, SPI only)

FIFO_EN

FIFO memory enable. Default value: 0.

(0: disabled; 1: enabled)

STOP_ON_FTH

Enable FIFO threshold level use. Default value: 0.

(0: FIFO depth is not limited; 1: FIFO depth is limited to threshold level)
