CONFIG_FXOS8700_PULSE_LTCY

Pulse latency

Type: hex

Help

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 high-pass filter configuration (HP_FILTER_CUTOFF[pls_hpf_en]). For ODR=800 Hz and pls_hpf_en=0, the resolution is 1.25 ms/LSB.
