CNTL3
Control register 3. Read/write control register that provides control of the Output Data Rate (ODR) for Tilt, Tap, and
Wake-up engines. Note that to properly change the value of these registers, the PC1 bit in CNTL1 register must first be
set to “0”.

OTP<1:0>
– ODR Tilt Position (OTP) sets the output data rate for the Tilt Position function per
Table
9 . The default Tilt Position ODR is 12.5Hz.

– ODR Tap/Double-Tap
TM
(OTDT) sets the output data rate for the Directional-Tap
TM
function per Table 10. The default Directional-Tap
TM
ODR is 400Hz.

Function Output Data Rate
OWUF<2:0>
– ODR Wake-Up Function (OWUF) sets the output data rate (per Table 11) at which the
wake up (motion detection) performs its function. The default Motion Wake-Up ODR is
0.781Hz.
Note1: ODR Wake-Up Function setting (OWUF<2:0>) needs to be less than or equal to
accelerometer ODR setting (OSA<3:0>) to avoid irregular resulting acceleration ODRs.
Note 2: If Advanced Data Path data is routed to the Wake-Up engine (ADPE = 1,
ADP_WB_ISEL = 1), OADP<3:0> also sets the ODR for the Wake-Up engines. In this case,
the ODR set by OWUF<2:0> is ignored.
