Filter Bits Setup
Identifier list mode:
0: FBITx bit is dominant bit
1: FBITx bit is recessive bit
Identifier mask bit mode:
0: FBITx is not used for comparison
1: FBITx must match
Note: The value of x is 0~31, indicating the bit number of FBIT.
Note: There are 28 sets of filters in product: i=0..27. Each set of filters consists of two 32-bit registers
and CAN_FiBANK [2:1]. The corresponding filter registers can be modified only when the corresponding
FACTx bit of CAN_FACT register is cleared or the FINITEN bit of CAN_FCTRL register is 1.
