Register description
Register description
The device contains a set of registers which are used to control its behavior and to retrieve
angular rate data. The register address, consisting of 7 bits, is used to identify them and to
write the data through the serial interface.

Output data rate selection. Refer to Table 21
Bandwidth selection. Refer to Table 21
Power-down mode enable. Default value: 0
(0: power-down mode, 1: normal mode or sleep mode)
Z-axis enable. Default value: 1
(0: Z-axis disabled; 1: Z-axis enabled)
Y-axis enable. Default value: 1
(0: Y-axis disabled; 1: Y-axis enabled)
X-axis enable. Default value: 1
(0: X-axis disabled; 1: X-axis enabled)
DR[1:0] is used for ODR selection. BW [1:0] is used for Bandwidth selection.
In Table 21 all frequencies resulting in combinations of DR / BW bits are given.
