In order to use this module, other parts of the system must be configured correctly, as described
below.
CANIF pins are multiplexed with other peripherals. User must first program the I/O Controller to
give control of the pins to the CANIF.
If the CPU enters a sleep mode that disables clocks used by CANIF, it will stop functioning and
resume operation after the system wakes up from sleep mode.
CANIF is connected to both the HSB and the PB, and therefore uses a HSB clock
(CLK_CANIF_HSB) and a PB clock (CLK_CANIF_PB). These clocks are generated by the
Power Manager. These clocks are enabled at reset, and can be disabled in the Power Manager.
CANIF uses a GCLK as clock source (CAN clock) for the CAN bus communication
(GCLK_CANIF). User must make sure this clock is running and frequency is correct before any
operation.
Messages can be stored in CPU or HSB RAM, so user must allocate RAM space for CAN
messages.
