Application Block Diagram
The pins used for interfacing the CAN may be multiplexed with the PIO lines. The programmer
must first program the PIO controller to assign the desired CAN pins to their peripheral function.
If I/O lines of the CAN are not used by the application, they can be used for other purposes by
the PIO Controller.
Table 40-2.
The programmer must first enable the CAN clock in the Power Management Controller (PMC)
before using the CAN.
A Low-power Mode is defined for the CAN controller. If the application does not require CAN
operations, the CAN clock can be stopped when not needed and be restarted later. Before stop-
ping the clock, the CAN Controller must be in Low-power Mode to complete the current transfer.
