Data Sheet
The 16-bit value allows for long inactivity detection times. The
maximum value is 0xFFFF or 65,535 samples. At the lowest output
data rate, 12.5 Hz, this equates to almost 90 minutes. In this con-
figuration, the accelerometer must be stationary for 90 minutes
before putting its system to sleep.
Address: 0x25, Reset: 0x00, Name: TIME_INACT_L
Address: 0x26, Reset: 0x00, Name: TIME_INACT_H
Setting the inactivity time to 0x00 has the same result as setting
this time to 0x01: Inactivity is detected when a single acceleration
sample has all axes lower than the inactivity threshold
(THRESH_INACT).
