NCCP
Whenever CAN bit is used as a measure of duration (e.g. MCR[FRZACK] and
MCR[LPMACK]), the number of peripheral clocks in one CAN bit can be calculated as:
where:
For example, 180 CAN bits = 180 x NCCP peripheral clock periods.
The following table gives an overview of the CAN compliant segment settings and the
related parameter values.
