51 * the expected sampling time to prevent the drifting.
54 * And because the sleep can't wake up _exactly_ at given time this would be
60 * delayed a lot. Yet, more we reserve the time for polling, more we also lose
62 * value is a balancing dance between severity of wasting CPU time and severity
69 * measurement time, checking the VALID bit and just sleeping again if the bit
72 * Downside is that the time-stamps would be very inaccurate as the wake-up
74 * result 'jumps' in the time-stamps when the delay drifted so that wake-up was
77 * timeout - and when the time-outs were very close to the actual sensor
78 * sampling, Eg. once in a blue moon, two consecutive time-outs would occur
103 * => Max total gain is HWGAIN * gain by integration time (8 * 4096) = 32768
137 * The IC has 5 modes for sampling time. 5 mS mode is exceptional as it limits
145 * the scale is doubled. Eg, time impact to total gain is x1, x2, x4, x8.
212 * Protect gain and time during scale adjustment and data reading.
