43 the timer used to generate the time stamps might have low resolution,
48 a high-resolution timer might use a counter that runs at a rate
58 different CPU cores on a multi-core or multi-processor system might be
60 synchronized, so packets time-stamped by different cores might not have

86 It can be set to 'active-low' (default) or 'active-high'.
87 Please note that the output pin is an open-drain output and it needs a
88 proper pull-up resistor to work.
107 driver supports both the low and the high resolution models.
109 The low resolution model (lm75) provides a 9 bit output with the LSB
