CANFDLLD_MCANMsgRAMCfgParams Struct Reference

Detailed Description

Data structure defines the MCAN Message RAM Configuration Parameters. Message RAM can contain following sections: Standard ID filters, Extended ID filters, TX FIFO(or TX Q), TX Buffers, TX EventFIFO, RX FIFO0, RX FIFO1, RX Buffer. Note: If particular section in the RAM is not used then it's size should be initialized to '0' (Number of buffers in case of Tx/Rx buffer).
