    /*
    To distinguish whether the filter is for standard or extended identifier. For extended identifiers the MSB of the code and mask are set.
    Description:
    Different ports may have different filters for a channel. If the CAN hardware cannot implement the filter, the driver virtualises filtering.
    Accept if ((id ^ code) & mask) == 0).
