Functions
bool	mscan_set_bit_rate (volatile mscan *m, unsigned can_bit_rate)
	Sets the bit rate for the MSCAN module m to can_bit_rate in [bits/s].
void	mscan_interrupts_disable (volatile mscan *m)
	Disables all interrupts for the MSCAN module m.
void	mscan_initialization_mode_enter (volatile mscan *m, mscan_context *context)
	Enter initialization mode for the MSCAN module m.
void	mscan_initialization_mode_leave (volatile mscan *m, const mscan_context *context)
	Leave initialization mode for the MSCAN module m.
void	mscan_sleep_mode_enter (volatile mscan *m)
	Enter sleep mode for the MSCAN module m.
void	mscan_sleep_mode_leave (volatile mscan *m)
	Leave sleep mode for the MSCAN module m.
bool	mscan_enable (volatile mscan *m, unsigned bit_rate)
	Enables and initializes the MSCAN module m.
void	mscan_disable (volatile mscan *m)
	Disables the MSCAN module m.
void	mscan_filter_clear (volatile mscan *m)
	Sets the filter ID and mask registers of the MSCAN module m to default values.
unsigned	mscan_filter_number (volatile mscan *m)
	Returns the number of active filters of the MSCAN module m.
bool	mscan_set_filter_number (volatile mscan *m, unsigned number)
	Sets the number of active filters of the MSCAN module m to number and returns true if number is valid.
volatile uint8_t *	mscan_id_acceptance_register (volatile mscan *m, unsigned i)
	Returns the address of the CANIDAR register with index i of the MSCAN module m.
volatile uint8_t *	mscan_id_mask_register (volatile mscan *m, unsigned i)
	Returns the address of the CANIDMR register with index i of the MSCAN module m.
bool	mscan_filter_operation (volatile mscan *m, bool set, unsigned index, uint32_t *id, uint32_t *mask)
	Sets or gets the filter ID and mask in id and mask depending on set of MSCAN module m. The filter is selected by the value of index.
void	mscan_get_error_counters (volatile mscan *m, unsigned *rec, unsigned *tec)
	Returns the receiver and transmitter error counter values in rec and tec of MSCAN module m.
