Hi,
The below FlexCAN driver API function using to set Receive message buffer ID mask type:
FLEXCAN_DRV_SetRxMaskType(flexcanInstance, kFlexCanRxMaskGlobal);
The FlexCAN MB mask has two types as below definition:
/*! @brief FlexCAN receive mask type.*/
typedef enum _flexcan_rx_mask_type {
kFlexCanRxMaskGlobal, /*!< Receive global mask*/
kFlexCanRxMaskIndividual /*!< Receive individual mask*/
} flexcan_rx_mask_type_t;
If customer want to use Receive individual mask, please use below code:
FLEXCAN_DRV_SetRxMaskType(flexcanInstance, kFlexCanRxMaskIndividual);
When using the FIFO, it will check FlexCAN control 2 register (CANx_CTRL2) register [MRP] bit ,
which is set the matching process starts from the Mailboxes and if no match occurs the matching
continues on the Rx FIFO.
Wish it helps.
Have a great day,
Ma Hui
