Description
Double-pulse abort.
0: Double-pulse detection is not aborted if the start of a pulse is detected during the time period specified by the
PULSE_LTCY register.
1: Setting the pls_dpa bit momentarily suspends the double-tap detection if the start of a pulse is detected during the
time period specified by the PULSE_LTCY register and the pulse ends before the end of the time period specified by
the PULSE_LTCY register.
Pulse event flag latch enable. When enabled, a read of the PULSE_SRC register is needed to clear the event flag.
0: Event flag latch disabled
1: Event flag latch enabled
Event flag enable on double-pulse event on Z-axis.
0: Event detection disabled
1: Raise event flag on detection of double-pulse event on Z-axis
Event flag enable on single-pulse event on Z-axis.
0: Event detection disabled
1: Raise event flag on detection of single-pulse event on Z-axis
Event flag enable on double-pulse event on Y-axis.
0: Event detection disabled
1: Raise event flag on detection of double-pulse event on Y-axis
Event flag enable on single-pulse event on Y-axis.
0: Event detection disabled
1: Raise event flag on detection of single-pulse event on Z-axis.
Event flag enable on double-pulse event on X-axis.
0: Event detection disabled
1: Raise event flag on detection of double-pulse event on X-axis.
Event flag enable on single-pulse event on X-axis.
0: Event detection disabled
1: Raise event flag on detection of single-pulse event on X-axis.
