TRANSIENT_SRC (0x1E) register

Transient event flag source register. This register provides the event status of the enabled axes and polarity (directional)

information.

Table 65. TRANSIENT_ CFG bit descriptions

Field

Description

tran_ele

Transient event flag latch enable. Default value: 0

0: Event flag latch disabled: the transient interrupt flag reflects the real-time status of the function.

1: Event flag latch enabled: the transient interrupt event flag is latched and a read of the TRANSIENT_SRC register is

required to clear the event flag.

tran_zefe

Z-axis transient event flag enable. Default value: 0

0: Z-axis event detection disabled

1: Z-axis event detection enabled. Raise event flag on Z-axis acceleration value greater than threshold.

tran_yefe

Y-axis transient event flag enable. Default value: 0

0: Y-axis event detection disabled

1: Y-axis event detection enabled. Raise event flag on Y-axis acceleration value greater than threshold.

tran_xefe

X-axis transient event flag enable. Default value: 0

0: X-axis event detection disabled

1: X-axis event detection enabled. Raise event flag on X-axis acceleration value greater than threshold.

tran_hpf_byp

Transient function high-pass filter bypass. Default value: 0

0: High-pass filter is applied to accelerometer data input to the transient function.

1: High-pass filter is not applied to accelerometer data input to the transient function.

Field

Description

tran_ea

Transient event active flag. Default value: 0

0: No transient event active flag has been asserted.

1: One or more transient event active flags has been asserted.

tran_zef

Z-axis transient event active flag. Default value: 0

0: Z-axis event flag is not active.

1: Z-axis event flag is active; Z-axis acceleration has exceeded the programmed threshold for the debounce time specified

in TRANS_COUNT.

tran_zpol

Z-axis event flag polarity.

0: Z-axis event was above positive threshold value.

1: Z-axis event was below negative threshold value.

tran_yef

Y-axis transient event active flag. Default value: 0

0: Y-axis event flag is not active.

1: Y-axis event flag is active; Y-axis acceleration has exceeded the programmed threshold for the debounce time specified

in TRANS_COUNT.

tran_ypol

Y-axis event flag polarity.

0: Y-axis event was above positive threshold value.

1: Y-axis event was below negative threshold value.

tran_xef

X-axis transient event active flag. Default value: 0

0: X-axis event flag is not active.

1: X-axis event flag is active; X-axis acceleration has exceeded the programmed threshold for the debounce time specified

in TRANS_COUNT.

tran_xpol

X-axis event flag polarity.

0: X-axis event was above positive threshold value.

1: X-axis event was below negative threshold value.
