I've been working with the LPC54616 CAN interfaces using the MCAN driver. The board I'm working with has a 12 MHz crystal and I'm using the PLL (BOARD_BootClockPLL180M) to boost the clock rate to 180 MHz.
I've implemented a number of CAN FD bit rates without problem. For CAN FD with a split rate I get 1 MBit/Sec - 3 MBit/Sec without issues.
Right now I'm trying to bump that up to 5 MBit/Sec for the data but haven't been successful. I haven't been able to find any clocking/speed specs on the LPC54616 CAN interfaces. I've tried a number of different dividers, segment values with the jump set to 3. So does someone know what the maximum bit rate for CAN FD data is or if 5MBit/Sec is possible?
Thanks in advance.
