	The maximum time interval that can elapse between the start of the
	acceleration on the selected channel exceeding the specified threshold
	and the end when the channel acceleration goes back below the specified
	threshold. The resolution depends upon the sample rate (ODR) and the

	ODR=800 Hz and pls_hpf_en=0, the resolution is 0.625 ms/LSB.

	The time interval that starts after the first pulse detection where the
	pulse-detection function ignores the start of a new pulse. The
	resolution depends upon the sample rate (ODR) and the highpass filter
	configuration (HP_FILTER_CUTOFF[pls_hpf_en]). For ODR=800 Hz and
	pls_hpf_en=0, the resolution is 1.25 ms/LSB.

	help
	The maximum interval of time that can elapse after the end of the
	latency interval in which the start of the second pulse event must be
	detected provided the device has been configured for double pulse
	detection. The detected second pulse width must be shorter than the
	time limit constraint specified by the PULSE_TMLT register, but the end
	of the double pulse need not finish within the time specified by the
	PULSE_WIND register. The resolution depends upon the sample rate (ODR)
	and the highpass filter configuration (HP_FILTER_CUTOFF[pls_hpf_en]).
	For ODR=800 Hz and pls_hpf_en=0, the resolution is 1.25 ms/LSB.
