Figure 48. Write 1 Timing
Figure 49. Read Timing
The precision of the generated clock is very important to get a proper behavior of the one-wire module.
This module is based on a state machine which undertakes actions at defined times.
The most stringent constraint is 0.0645 as a relative time imprecision.
The time relative precision is directly derived from the frequency of the derivative clock (f):
Time relative precision = 1/f -1 = divider/clock (MHz) - 1
The Table 37 gathers relative time precision for different main clock frequencies.
