| The maximum time interval that can elapse between the start of the |

| 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. |
