Clock Control
indicates the minimum operating frequencies in MHz for
f
CAN
that are
required for a baud rate of 1 Mbit/s for the active CAN nodes. If less baud rate is desired,
the values can be scaled linearly (e.g. for a maximum of 500 kbit/s, 50% of the indicated
value are required).
The values imply that the CPU executes maximum access to the MultiCAN module. The
values may contain rounding effects.
