Table 137. FUNCTIONS_ENABLE register description

INTERRUPTS_ENABLE

Enables basic interrupts (6D/4D, free-fall, wake-up, tap, activity/inactivity). Default value: 0

(0: interrupt disabled; 1: interrupt enabled)

TIMESTAMP_EN

Enables timestamp counter. The counter is readable in TIMESTAMP0 (40h), TIMESTAMP1 (41h),

TIMESTAMP2 (42h), and TIMESTAMP3 (43h). Default value: 0

(0: disabled; 1: enabled)

DIS_RST_LIR_ALL_INT

When this bit is set to 1, reading the ALL_INT_SRC (1Dh) register does not reset the latched

interrupt signals. This can be useful in order to not reset some status flags before reading the

corresponding status register. Default value: 0

(0: disabled; 1: enabled)

INACT_EN_[1:0]

Enables activity/inactivity (sleep) function. Default value: 00

(00: stationary/motion-only interrupts generated, accelerometer and gyroscope configuration do not

change;

01: sets accelerometer to low-power mode 1 with accelerometer ODR selected through the

XL_INACT_ODR_[1:0] bits of the INACTIVITY_DUR (54h) register, gyroscope configuration does

not change;

10: sets accelerometer to low-power mode 1 with accelerometer ODR selected through the

XL_INACT_ODR_[1:0] bits of the INACTIVITY_DUR (54h) register, gyroscope in sleep mode;

11: sets accelerometer to low-power mode 1 with accelerometer ODR selected through the

XL_INACT_ODR_[1:0] bits of the INACTIVITY_DUR (54h) register, gyroscope in power-down

mode)
