The basic SPC protocol unit time granularity is defined as 3 µs. Every timing is a multiple
of this basic time unit. To achieve more flexibility, trimming of the unit time can be used
to:
• Allow a calibration trim within a timing error of less than 20% clock error (as given in
• Allow a modification of the unit time for small speed adjustments
This enables a setup of different unit times, even if the internal RC oscillator varies by
±20%. Of course, timing values that are too low could clash with timing requirements of
the application and should therefore be avoided, but in principle it is possible to adjust
the timer unit for a more precise protocol timing. The output characteristic depends on
the external load, the wiring, as well on the pull-up voltage and the temperature.
Furthermore, sufficient driving capability of the sensor counterpart (ECU) is mandatory,
