6.15 0x13: CTRL_REG1
The CTRL_REG1 register is used to configure the device ODR, set the operating mode,
and exercise the self-test and zero-rate offset adjustment functions.
NOTE
Control bits in CTRL_REG1 should be changed only in
Standby or Ready mode. Accuracy of the data is not
guaranteed if these bits are changed when the device is in
Active mode.

Description
7
ZR_cond
Zero-rate condition
• Used to trigger the offset compensation. For this reason, it is meant to be used only when the
device is in zero rate condition on all axes.
• Writing a 1 to this bit initiates the internal zero-rate offset calibration.
• Self-clears after the zero-rate offset calculation, and it can only be used once after a hard or soft
reset has occurred. In order to use the ZR_cond a second time, the device has to be reset either
with a hard or soft reset.
6
RST
Software Reset
• Causes a synchronous reset of the device.
• On reset, all registers revert to their default values.
• Self cleared after assertion.
0: Device reset not triggered/completed
1: Device reset triggered
