CTRL_REG9 (23h)

Control register 9.

Table 69. CTRL_REG8 register description

BOOT

Reboot memory content. Default value: 0

(0: normal mode; 1: reboot memory content(1))

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

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

BDU

Block Data Update. Default value: 0

(0: continuous update; 1: output registers not updated until MSB and LSB read)

H_LACTIVE

Interrupt activation level. Default value: 0

(0: interrupt output pins active high; 1: interrupt output pins active low)

PP_OD

Push-pull/Open Drain selection on INT pin. Default value: 0

(0: push-pull mode; 1: open drain mode)

SIM

SPI Serial Interface Mode selection. Default value: 0

(0: 4-wire interface; 1: 3-wire interface).

IF_ADD_INC

serial interface (I2C or SPI). Default value: 1

(0: disabled; 1: enabled)

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)

Table 70. CTRL_REG9 register

0(1)

1. These bits must be set to ‘0’ for the correct operation of the device

SLEEP_G

0(1)

FIFO_

TEMP_EN

DRDY_

mask_bit

I2C_disable FIFO_EN

STOP_ON

_FTH

Table 71. CTRL_REG9 register description

SLEEP_G

Gyroscope sleep mode enable. Default value: 0

(0: disabled; 1: enabled)

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

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

DRDY_mask_bit Data available enable bit. Default value: 0

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

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)
