Field Documentation
 uint16_t CAN_FilterInitTypeDef::CAN_FilterIdHigh
 Specifies the filter identification number (MSBs for a 32-bit configuration, first
one for a 16-bit configuration). This parameter can be a value between 0x0000
and 0xFFFF
 uint16_t CAN_FilterInitTypeDef::CAN_FilterIdLow
 Specifies the filter identification number (LSBs for a 32-bit configuration, second
one for a 16-bit configuration). This parameter can be a value between 0x0000
and 0xFFFF
 uint16_t CAN_FilterInitTypeDef::CAN_FilterMaskIdHigh
 Specifies the filter mask number or identification number, according to the mode
(MSBs for a 32-bit configuration, first one for a 16-bit configuration). This
parameter can be a value between 0x0000 and 0xFFFF
 uint16_t CAN_FilterInitTypeDef::CAN_FilterMaskIdLow
 Specifies the filter mask number or identification number, according to the mode
(LSBs for a 32-bit configuration, second one for a 16-bit configuration). This
parameter can be a value between 0x0000 and 0xFFFF
 uint16_t CAN_FilterInitTypeDef::CAN_FilterFIFOAssignment
 Specifies the FIFO (0 or 1) which will be assigned to the filter. This parameter
can be a value of CAN_filter_FIFO
 uint8_t CAN_FilterInitTypeDef::CAN_FilterNumber
 Specifies the filter which will be initialized. It ranges from 0 to 13.
 uint8_t CAN_FilterInitTypeDef::CAN_FilterMode
 Specifies the filter mode to be initialized. This parameter can be a value of
CAN_filter_mode
 uint8_t CAN_FilterInitTypeDef::CAN_FilterScale
 Specifies the filter scale. This parameter can be a value of CAN_filter_scale
 FunctionalState CAN_FilterInitTypeDef::CAN_FilterActivation
 Enable or disable the filter. This parameter can be set either to ENABLE or
DISABLE.
