NAME
Tilt debounce filtering is disabled. The device updates portrait/landscape every reading at the rate set by AMSR[2:0] or
AWSR[1:0]
2 measurement samples at the rate set by AMSR[2:0] or AWSR[1:0] have to match before the device updates portrait/
landscape data in TILT (0x03) register.
3 measurement samples at the rate set by AMSR[2:0] or AWSR[1:0] have to match before the device updates portrait/
landscape data in TILT (0x03) register.
4 measurement samples at the rate set by AMSR[2:0] or AWSR[1:0] have to match before the device updates portrait/
landscape data in TILT (0x03) register.
5 measurement samples at the rate set by AMSR[2:0] or AWSR[1:0] have to match before the device updates portrait/
landscape data in TILT (0x03) register.
6 measurement samples at the rate set by AMSR[2:0] or AWSR[1:0] have to match before the device updates portrait/
landscape data in TILT (0x03) register.
7 measurement samples at the rate set by AMSR[2:0] or AWSR[1:0] have to match before the device updates portrait/
landscape data in TILT (0x03) register.
8 measurement samples at the rate set by AMSR[2:0] or AWSR[1:0] have to match before the device updates portrait/
landscape data in TILT (0x03) register.

For portrait/landscape detection: The device takes and averages 32 g-cell measurements every 31.25 ms in
Auto-Wake. The update rate is 32 samples per second. These measurements update the XOUT (0x00), YOUT
(0x01), and ZOUT (0x02) registers also.
For portrait/landscape detection: The device takes and averages 32 g-cell measurements every 62.5 ms in
Auto-Wake. The update rate is 16 samples per second. These measurements update the XOUT (0x00), YOUT
(0x01), and ZOUT (0x02) registers also.
For portrait/landscape detection: The device takes and averages 32 g-cell measurements every 125 ms in
Auto-Wake. The update rate is 8 samples per second. These measurements update the XOUT (0x00), YOUT
(0x01), and ZOUT (0x02) registers also.
For portrait/landscape detection: The device takes and averages 32 g-cell measurements every 1000 ms in
Auto-Wake. The update rate is 1 sample per second. These measurements update the XOUT (0x00), YOUT
(0x01), and ZOUT (0x02) registers also.
