I was trying to use RX Fifo for K30D10 FlexCan module. Reference manual says there is 64 MB could be use and up to 128 Fifo Filter could be use. But, I realized that I cannot use more then 16 MB. I could not reach CS16 register in example. At CTRL2[RFFN] register there is a table. RFFN could be 3 maximum. But there is nothing about this limitation. Do I have to something to use full functional CAN?
