Field

Description

pls_dpa

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.

pls_ele

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

pls_zdpefe

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

pls_zspefe

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

pls_ydpefe

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

pls_yspefe

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.

pls_xdpefe

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.

pls_xspefe

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.
