When ODR[2,0] are set to ‘000’ the device enables One-Shot mode. When the ONESHOT
bit is set to 1 in CTRL_REG2 (11h),a new conversion for pressure and temperature starts.
An ODR change will not flush FIFO content.
The BDU bit is used to inhibit the update of the output registers between the reading of upper
and lower register parts. In default mode (BDU = ‘0’), the lower and upper register parts are
updated continuously. When the BDU is activated (BDU = ‘1’), the content of the output
registers is not updated until both MSB and LSB are read which avoids reading values
related to different samples.
The SIM bit selects the SPI serial interface mode:
0: (default value) 4-wire SPI interface mode selected
1: 3-wire SPI interface mode selected
