BOOT

Reboot memory content. Default value: 0

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

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

(0: Data LSbyte @lower address; 1: Data MSbyte @ lower address)

SIM

SPI Serial Interface Mode configuration. Default value: 0

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

ODU

Output Data Update. Default value: 0

(0: output registers not updated until MSB and LSB have been read;

1: OIS output registers are updated continuously)

ORIENT

Directional orientation selection. Default value: 0

(0: X-axis - Y-axis; 1: Y-axis - X-axis)

PW[1:0]

Power mode selection. Default: 00
