ATSAME70N20B MCAN Event fifo missing timestamps

I have a problem with only some timestamps being returned in the event fifo, it appears to be randomly skipping 1 or more timestamps, occasionally it works as expected for a few packets before skipping again. Discontinuities can be seen in the message markers but the MCAN_TXEFS.EFGI is continuous so it appears the problem is in hardware, the timestamp bit is set in all transmitted packets. I'm using the newest MPLABX and MHC.

    Seems like MCAN_TXEFC_EFWM(0) instead of MCAN_TXEFC_EFWM(1) fixed this issue
