SIM

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

ODR[2:0]

Output data rate selection. Default value: 000

Refer to Table 17.

EN_LPFP

Enable low-pass filter on pressure data. Default value: 0

(0: Low-pass filter disabled; 1: Low-pass filter enabled)

LPFP_CFG

Low-pass configuration register. Default value: 0

Refer to Table 18.

BDU(1)

Block data update. Default value: 0

(0: continuous update;

1: output registers not updated until MSB and LSB have been read)

SIM

SPI Serial Interface Mode selection. Default value: 0

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

1. To guarantee the correct behavior of the BDU feature, PRESS_OUT_H (2Ah) must be the last address

read.
