--CAN_FilterNumber
CAN_FilterNumber selects the filter which will be initialized. It ranges from 0 to 13.

|CAN_FilterMode Description
CAN_FilterMode_IdMask id/mask mode
CAN_FilterMode_IdList identifier list mode
--CAN_FilterMode
CAN_FilterScale Description
CAN_FilterScale_Two16bit Two 16-bit filters
CAN_FilterScale_One32bit One 32-bit filter
--CAN_FilterScale
CAN_FilterIdHigh is used to select the filter identification number (MSBs for a 32-bit configuration, first one for a 16-bit configuration).
0x0000 to 0xFFFF
--CAN_FilterIdHigh
CAN_FilterIdLow is used to select the filter identification number (LSBs for a 32-bit configuration, second one for a 16-bit configuration).
--CAN_FilterIdLow
0x0000 to 0xFFFF
--CAN_FilterMaskIdHigh
CAN_FilterMaskIdHigh is used to select the filter mask number or identification number,
according to the mode (MSBs for a 32-bit configuration, first one for a 16-bit configuration). It
ranges from 0x0000 to 0xFFFF.
--CAN_FilterMaskIdLow
CAN_FilterMaskIdLow
CAN_FilterMaskIdLow is used to select the filter mask number or identification number,
according to the mode (LSBs for a 32-bit configuration, second one for a 16-bit
configuration). It ranges from 0x0000 to 0xFFFF.
--CAN_FilterFIFOAssignment
CAN_FilterFIFO Description
CAN_FilterFIFO0 Filter FIFO 0 assignment for filter x
CAN_FilterFIFO1 Filter FIFO 1assignment for filter x
--FunctionalState CAN_FilterActivation
CAN_FilterActivation
CAN_FilterActivation enables or disables the filter. It can be set either to ENABLE or
DISABLE.
